Thanks @All.
Option C is the only correct answer.
Option C is the only correct answer.

The chemical reaction is supposed to occur between cement and water. Both aggregates (fine and course) should be chemically inert if they react will make concrete unsound and weak.
Hence, the given answer is correct.
Hence, the given answer is correct.

Only C is the right answer because when we add water with cement chemical reaction will start between water and cement. This process is known as the heat of hydration. And this is also known as an exothermic reaction. In this reaction, heat is liberated so this reaction name is the heat of hydration.

Option C is correct because in option A the cement doesn't chemically react with aggregates. And in option B the evaporation from concrete in submerged structures doesnt occur but strength is gained. And the hydration of cement is the only correct option.

The chemical reaction of cement is only with water (called as hydration of cement).
And how evaporation can help in gain strength.
Only C option is correct.
And how evaporation can help in gain strength.

In concrete aggregate and sand are also called non-reactivate materials so option C is the only correct answer.

Aggregate are inert material. They don't take part in chemical reaction.
