Options

A. hasn’t
B. haven’t
C. couldn’t
D. Didn’t

Explanation

According to the Question Tag rules, If the sentence is positive, the question tag must be negative and vice versa. The sentence and the question tag must be in the same tense. Whereas, for negative question tags, the contracted form( haven’t, hasn’t, aren.t, won’t) of the helping verb will be used. Similarly in the given question, the sentence is positive, the question tag must be negative and in the contracted form. Hence, “ haven’t” will be the most appropriate answer.
