7 0

Answer:

d. 4.

Explanation:

Hello,

In this case, the required number on milligrams is:

$0.007502x10^{-26}g*\frac{1000mg}{1g}=7.502x10^{-26}mg$

It means that it has four significant figures which are counted for 7, 5, 0 and 2, considering that zero as it is to the right of first nonzero digit (7).

Regards.
