Option (B)

Explanation:

A delta is usually defined as a contrasting geological landform that forms the mouth of a river channel, and where there is an abundant supply of sand, clay and silt-size particles. The deltas are the places where the river finally mixes with seas or oceans. These areas form a flat lowland that is comprised of highly fertile soil and is suitable to carry out agricultural activities.
