The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options. If you don’t find any error, mark ‘No error’ as your answer.
After a lengthy conversation which was / filled with laughter and reminiscence, / they reluctantly hang up the phone.

Correct option is D

✔️ Option (d) they reluctantly hang up the phone contains the error.
· Explanation:
· The sentence begins in the past tense: “was” and “filled” both indicate past events.
· “Hang up” is in the present tense, which breaks the tense consistency of the sentence.
· The correct verb form should be “hung up” (past tense of hang when referring to ending a call).
· Grammatical rule used:
· In a sentence, all actions should generally be in the same tense unless there's a clear shift in time.
· Hang up (present) → Hung up (past) when aligning with past narrative.
· ✦ Hindi Explanation: यदि वाक्य का प्रारंभ भूतकाल में है (जैसे "was", "filled"), तो अंत का क्रिया रूप भी भूतकाल में ही होना चाहिए। "hang up" को "hung up" में बदलना चाहिए।
· Meanings of all the other parts:
· (a) filled with laughter and reminiscence – ✅ Grammatically correct; "filled" is past tense.
· (b) No error – ❌ Incorrect choice; there is a tense error in part (d).
· (c) After a lengthy conversation which was – ✅ Correct introductory clause in past.
