Choose the grammatically correct sentence:

The correct answer is Option (2) → It was such a windy evening at the beach that our paper plates kept flying away.

“Such a” + adjective + noun:

• We use such a before an adjective that comes with a singular noun.
• Here the adjective “windy” comes with the noun “evening”. So “such a windy evening” is correct.

Why the Other Options are Incorrect?

Option 1: The conductor asked who’s bag was lying under the last seat of the bus. — Incorrect. “Who’s” is the short form of “who is”. To ask about the owner of something, we need “whose”.
Corrected: The conductor asked whose bag was lying under the last seat of the bus.

Option 3: Many children in our colony are addicted with mobile games. — Incorrect. “Addicted” is always followed by “to”, not “with”.
Corrected: Many children in our colony are addicted to mobile games.

Option 4: The fruit seller packed three dozens bananas for the temple prasad. — Incorrect. After a number, “dozen” does not take -s.
Corrected: The fruit seller packed three dozen bananas for the temple prasad.
