Add the appropriate question tag from the given options. It isn't rea…

The correct answer is Option (3) → is it ?

Question tags:

• A question tag repeats the helping verb of the statement and uses a pronoun for the subject.
• Polarity is reversed:
  • Positive statement → negative tag.
  • Negative statement → positive tag.
• This sentence: "It isn't ready yet" is negative and its verb is is, so the tag is positive: is it?

Complete sentence: It isn't ready yet, is it?

Why the Other Options are Incorrect?

Option 1: did it ? — Incorrect. "did" is past and belongs to sentences with a main verb in the simple past. The statement uses "is".

Option 2: hasn't it ? — Incorrect.

• "has" does not match the verb "is".
• A negative statement needs a positive tag, not "hasn't".

Option 4: can't it — Incorrect. The statement has no "can", and the tag after a negative statement must be positive.
