Solution

The correct option is D Statement 1 is not correct but Statement 2 is correct.
Answer(D)

The entropies of gases are much larger than those of liquids, which are larger than those of solids so when solid is dissolved it mixes with liquid phase hence entropy increases. so statement 1 is not correct.
It is true that liquid particles are less ordered and have more random motion than solid particals
