BIt increases.
CIt remains constant.
DIt varies depending on location.

Verified Answer :

it decreases .
I did this problem just now on USA test prep

Answer: The correct option is A.

Explanation:

In solid state, the atoms are tightly packed due to the strong force of attraction between its molecules.

In liquid state, the atoms are not tightly packed due to the less force of attraction between its molecules as compared in solid state.

In the given problem, matter changes state from solid to liquid then the force of attraction between its molecules decreases.

Therefore, the correct option is A.
