The statement below is followed by four options. Each option is related to the item in the statement, but only one is always true. Select the option that always holds and makes the statement true.
"A river always has ______."
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Banks
The answer must hold for every river, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) Delta — formed only where a river drops a lot of silt at its mouth; many rivers have no delta, for example the Narmada and the Tapi, which end in estuaries.
Option (2) Tributaries — many rivers have them, but a small stream need not be joined by any tributary.
Option (3) Banks — a river flows in a channel, and the sides of that channel are its banks. Without banks there is no channel and no river, so this is always true.
Option (4) Fishes — a polluted or seasonal river can have no fish at all.
