Key Points

  • As the river approaches the sea, the water speed decreases, and it begins to break up into several streams called distributaries. The rivers become so slow it begins to deposit its load.

  • The collection of sediments of all the distributaries at the mouth forms a delta of the river. Each distributary forms its own mouth.

  • A distributary is a stream that breaks down from a running river and does not join it back. This usually happens, when a river is about to reach a sea or an ocean and is losing its speed as a result of the same. Hoogli river is a distributary of Ganges river.

Hence, the correct option is 'C'.
