Choose the grammatically correct sentence:

The correct answer is Option (3) → The last bell had rung before we reached the school gate.

The past participle (V3) comes after “has”, “have” and “had”:

• After “has”, “have” or “had”, the main verb takes the V3, not the simple past (V2).
• The forms of “ring” are ring – rang – rung. This sentence has “had rung”, which is right.

Why the Other Options are Incorrect?

Option 1: By the time Papa reached the wedding hall, most of the guests had went home. — Incorrect. The given sentence says “had went”. “Went” is the V2 of “go”. After “had”, the V3 “gone” is needed.
Corrected: By the time Papa reached the wedding hall, most of the guests had gone home.

Option 2: My cousin from Jaipur has came to stay with us for the summer holidays. — Incorrect. The given sentence says “has came”. The forms of “come” are come – came – come. After “has”, the V3 “come” is needed.
Corrected: My cousin from Jaipur has come to stay with us for the summer holidays.

Option 4: The children have drank all the mango juice in the fridge. — Incorrect. The given sentence says “have drank”. The forms of “drink” are drink – drank – drunk. After “have”, the V3 “drunk” is needed.
Corrected: The children have drunk all the mango juice in the fridge.
