Target question: What is the value of (x-0.5)?
Statement 1: (6x-3)^2 = 0
=> 6x = 3
=> x = 0.5
=> x-0.5 = 0.5-0.5 = 0 Definitive answer
Sufficient
Statement 2: x^2 - 0.25 = 0
=> x = + 0.5 or - 0.5
=> x-0.5 = 0 or -1 ....No definitive answer
Not Sufficient
OA should be A.

(A) is the correct answer IMO
Statement (1) (6x - 3)^2 = 0
6x = 3 ; x= 1/2
Sufficient
Statement (2) x^2 - 0.25 = 0
x = +- 1/2
Not sufficient
Statement (1) (6x - 3)^2 = 0
6x = 3 ; x= 1/2
Sufficient
Statement (2) x^2 - 0.25 = 0
x = +- 1/2
Not sufficient
