(A) above
(B) at
(C) over
(D) on

Choose the correct answer from the options given below:

(D) Only

The correct answer is Option (3) → (D) Only

• The correct preposition to use when referring to a city located along the side of a river is "on".
• Example: "Calcutta is on the banks of the river Hooghly."

OTHER OPTIONS

• (A) Above  → Incorrect, because "above" suggests a higher position, which does not fit here.
• (B) At  → Incorrect, because "at" is used for specific points rather than locations along a river.
• (C) Over  → Incorrect, because "over" means on top of or covering something, which does not fit.
