Add a suitable question tag to the following sentence from the option…

The correct answer is Option (4) → Doesn't he?

Question tags with the simple present:

• A question tag repeats the helping verb of the statement and uses a pronoun for the subject.
• When the statement has no helping verb (simple present or simple past), the tag uses do/does/did:
  • "Lives" is simple present, third person singular, so does.
  • Mohit becomes he.
• A positive statement takes a negative tag: doesn't he?

Complete sentence: Mohit lives in the city, doesn't he?

Why the Other Options are Incorrect?

Option 1: Did he? — Incorrect. "Did" is the past tense, but "lives" is in the present. The tag is also positive.

Option 2: Does he? — Incorrect. The helping verb is right, but a positive statement needs a negative tag.

Option 3: Will he? — Incorrect. "Will" belongs to the future tense, which the statement does not use, and the tag is positive.
