Among the following, which is closest to $\sqrt{0.016}$?

Among the following, which is closest in value to $\sqrt{0.016}$?

A. $0.4$

B. $0.04$

C. $0.2$

D. $0.02$

E. $0.13$

My Approach:

$(\frac{16}{1000}{)}^{\frac{1}{2}}=(\frac{4}{250}{)}^{\frac{1}{2}}=\frac{2}{5\cdot \sqrt{10}}=\frac{\sqrt{2}}{5\cdot \sqrt{5}}$

But I don't know how to reach to answer.

Thank You!
