(i). a² – 9a + 20 = 0,
(ii). 2b² – 5b – 12 = 0 to solve both the equations to find the values of a and b?

A. If a < b
B. If a ≤ b
C. If the relationship between a and b cannot be established
D. If a ≥ b

Explanation:

I. (a – 5)(a – 4) = 0
=> a = 5, 4
II. (2b + 3)(b – 4) = 0
=> b = 4, -3/2 => a ≥ b
