A. Quartzite
B. Slate
C. Gneiss
D. Schist
E. Diorite ✓
Submitted by: Mansoor Ul Haque
All f the above are Metamorphic rocks while Diorite is the name used for a group of coarse-grained igneous rocks with a composition between that of granite and basalt. It usually occurs as large intrusions, dikes, and sills within continental crust. These often form above a convergent plate boundary where an oceanic plate subducts beneath a continental plate.

IF YOU THINK THAT ABOVE POSTED MCQ IS WRONG.
PLEASE COMMENT BELOW WITH CORRECT ANSWER AND ITS DETAIL EXPLANATION.
all are metamorphic rock including quartzite:
Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.
Thanks for correction
Kindly update this question
All of the above options are Metamorphic rocks.
There are two basic types of metamorphic rocks. Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance. Pictures and brief descriptions of some common types of metamorphic rocks are shown on this page.
Thanks for correction
Quartzite is a metamorphic rock formed by the metamorphism of quartz sandstone, infact slate, schist and gniess all are metamorphic rocks
please correct it
Thanks for correction. option E is added now
Answer is wrong because quartzite is also an example of metamorphic rocks.
Quartzite is a Metamorphic rock.

Thanks
All of the above mentioned rocks in option are Metamorphic Rocks.
Quartzite is a metamorphic form of Sand stone.
Thanks. answer updated
Which of these is not a Metamorphic rock?
A. Quartzite
B. Slate
C. Gneiss
D. Schist
Correct answer is all of these. Admin please respond
Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone.[1][2] Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe2O3). Other colors, such as yellow, green, blue and orange, are due to other minerals.
sorry correct answer should be none meaning all of these are metamorphic rocks
Thanks dear Hamza for correction
Quartzite is a metamorphic rock. kindly Correct it.
Quartzite, slate, gneiss and schist are metamorphic rock. So above mcq is incorrect.
A. Quartzite
B. Slate
C. Gneiss
D. Schist
these all are metamorphic rocks
Sedimentary
Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contains fossils.
Examples of this rock type include conglomerate and limestone.
Metamorphic
Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). The rocks that result from these processes often have ribbonlike layers and may have shiny crystals, formed by minerals growing slowly over time, on their surface.
Examples of this rock type include gneiss and marble.
Igneous
Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals form and the rock looks shiny and glasslike. Sometimes gas bubbles are trapped in the rock during the cooling process, leaving tiny holes and spaces in the rock.
Examples of this rock type include basalt and obsidian.
these are all metamorphic rocks.
