Answer:

A. Water reacts with iron minerals in rock to form rust.

Explanation:

Generally, weathering is the process by which rocks are broken down or disintegrated into smaller particles. However, as the name implies, chemical weathering is the weathering facilitated by chemical reactions.

However, there are various types of chemical weathering, of which one is HYDRATION. Hydration is a type of chemical weathering which involves the reaction of water with the chemical constituents of rocks, which eventually disrupt or changes the structure. Therefore, in chemical weathering, water reacts with iron minerals in rock to form rust.
