What is the role of deposition in delta formation by Peninsular rivers?

Correct answer: Sediments deposited at the mouth form a delta

The direct answer is B: sediments deposited at the river mouth form a delta. A river carries small particles of soil, sand and rock called sediments. Near its mouth, the river enters a sea or lake, becomes slower and loses carrying power. The sediments then settle and accumulate. Over time, this deposited material may build a low, often triangular or branching landform called a delta. A is wrong because deposition cannot turn a river into a glacier; a glacier is moving ice. C is wrong because deposition adds material and does not automatically dry the entire river. D is wrong because deposition does not make a river rise from the sea; it builds land where the river meets the water body. B states the actual cause-and-result relationship. Memory cue: slower water means more settling, and settling at the mouth means delta.
