Concept:Question tags must match the main statement’s auxiliary verb and its positive or negative form.
Explanation:Each option is a possible question tag with a different use.
Option A “is he” follows a negative statement containing “is”.
Option B “isn’t he” follows a positive statement containing “is”.
Option C “doesn’t he” follows a positive statement containing “does”.
Option D “does he” follows a negative statement containing “does”.
However, the actual sentence stem that needs to be completed is missing from the question.
Without the stem, the tense, the auxiliary verb, and the positive or negative nature of the statement cannot be identified.
As a result, it is impossible to determine which option is correct.
Answer:The correct answer cannot be determined because the sentence stem is not provided.
