- ADelta
- BTributaries
- CBoats
- DBanks
Solution & Step-by-step Explanation
We need to determine the feature that is a mandatory characteristic of any river:
* Banks: A river is a natural flowing watercourse. For water to flow continuously as a stream or river, it must be confined within lateral boundaries. These land boundaries bordering the channel are called banks. Without banks, the water would spread out across the land as a flat flood or a lake rather than a defined flowing river.
* Delta: A delta forms at the mouth of some rivers where they enter an ocean or lake, but many rivers do not form deltas.
* Tributaries: Many streams or rivers do not have smaller streams flowing into them.
* Boats: Boats are man-made objects for transportation and are completely optional.
Hence, a river always has banks.
