**(i). a**

(ii). b

^{2}– 7a + 12 = 0,(ii). b

^{2}– 3b + 2 = 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 (Correct)**

Explanation:

I.(a – 3)(a – 4) = 0

=> a = 3, 4

II. (b – 2)(b – 1) = 0

=> b = 1, 2

=> **a > b**
