Add the appropriate question tag from the given options.

It isn't ready yet, ________?

is it ?

The given statement is a negative sentence in the present simple tense. In English, when forming a question tag for a negative statement in the present simple tense, we use the positive form of the auxiliary verb. In this case, the auxiliary verb is "isn't" (a contraction of "is not"). Therefore, the correct question tag is "is it?"

• Did it? makes sense grammatically, but it implies the action already happened in the past, which isn't the case here. "Yet" indicates that it's not ready at the present moment.
• Hasn't it? flips the sentence to the negative, which doesn't match the intended meaning. You're not trying to confirm the negative, but seeking confirmation of the positive statement.
• Can't it? suggests an inability, whereas the sentence is about the current state of being ready, not about potential.
