Option D - 25

Step-by-step explanation:

Given : A sample of rock is found to contain 100 grams of a parent isotope.

To find : How many grams of the parent isotope will remain after two half-lives.

Solution : A sample of rocks contain parent isotope = 100 gram

After one half life of the parent isotope i.e. divided by 2

$\frac{100}{2}=50$

After two half lives of the parent isotope means again divide one-half life by 2

$\frac{50}{2}=25$

Which means 25 gram of the parent isotope will remain after two half lives.

Therefore, Option D is correct -25
