Option A. 5/8 is the correct answer.

Step-by-step explanation:

Square root by factorization will be used to solve this question.

Given

$\sqrt{\frac{25}{64}}$

The square root can be applied to numerator and denominator separately

$=\frac{\sqrt{25}}{\sqrt{64}}$

Factorization

$=\frac{\sqrt{5*5}}{\sqrt{2*2*2*2*2*2}}\\=\frac{\sqrt{5^2}}{\sqrt{2^2*2^2*2^2}}\\=\frac{5}{2*2*2}\\=\frac{5}{8}$

Hence,

Option A. 5/8 is the correct answer.
