Weathering of rocks is an example of Mineral carbonation.

Here's why:

a. Soil sequestration: This involves the process of capturing carbon dioxide directly from the atmosphere and storing it in soil organic matter. It's not directly related to the weathering of rocks.

b. Geological sequestration: This involves injecting carbon dioxide deep underground into porous rock formations. While rocks are involved, it's not about their weathering.

c. Mineral carbonation: This is the correct answer. It's the process of reacting carbon dioxide with magnesium or calcium silicate minerals to form a solid carbonate. This process often occurs naturally over geological timescales and is responsible for much of the weathering of rocks.

d. Hydrological sequestration: This involves the storage of carbon in aquatic systems, like oceans and reservoirs. It's not directly related to the weathering of rocks.
