Solution
The correct option is A Imbibition
Imbibition is a physical process in which dry surface absorbs water. In rocks, the dead material absorbs water resulting in the increase in volume, which splits the rock. This process is the primary force responsible for cracking of rocks in nature and leads to weathering of rocks. Weathering of rocks is an important step in soil formation.
