The OA is "A", so i guess its typo in the q.

A can be the value of x. But, B cannot be. as from B x = 1/4 and sqrt(x) = 1/2 and x < 1/2. Hence, to me, there is no typo in the question.

yes but 1/2 < 1/2 is false...

hence according to q it cannot represent x.

A. if x = 1/4, sqrtx = 1/2
B. if x = 1/2, sqrtx = 1/sqrt2, which is greater than 1/2.

so x = 1/4 is definitely not possible but x = 1/2 is even not possible.

Correct me if I'm wrong but if you square everything you end up with
0<x<1/4
so unless it said, 0<x (less than or equal to)1/4, you will have two answers 1/2 or 1/4.....

Both A & B CANNOT be correct since:

0 < sqrt of x < 1/2

A.- 1/2 => sqrt of 1/2 = 0,707 therefore sqrt of 1/2 is more than 1/2 (0,5).

B.- 1/4 => sqrt of 1/4 = 0,5 therefore sqrt of 1/4 is equal to 1/2 (0,5).

Could you tell us the source of this question?
