Correct option is C
The correct substitution of the highlighted words is (c)
didn’t she.
Explanation: The given sentence is an example of a
question tag. The main clause “She told you an interesting story” is affirmative, so its question tag must be
negative and use the
auxiliary verb ‘did’ because the main verb is in the past simple tense (“told”). Hence, the correct tag is
“didn’t she”.
Grammatical rule used:
A question tag follows this pattern:
· If the main clause is
positive, the tag is
negative.
· If the main clause is
negative, the tag is
positive.
· Example:
You went there, didn’t you?
·
Information booster: In tag questions,
the auxiliary verb of the main clause (or ‘do/does/did’ if there is none) is repeated in the tag.
