Parts of the given sentence have been given as options. One of them may contain a grammatical error. Select the option that has the error. If there is no error, select ‘No error’.
Your mother prepares delicious food, did she?

Correct option is D

Option (d) contains an error.
· The error is in the tag question "did she?" which is incorrect because the main clause is in the present tense ("prepares"). The correct tag should match the tense of the main verb, so it should be "doesn't she?" instead of "did she?".
Grammatical Rule Used: In tag questions, the auxiliary verb in the tag must match the tense of the main verb in the sentence. If the main verb is in the present tense, the auxiliary in the tag should also be in the present tense.
Example: Incorrect: She likes ice cream, didn't she? Correct: She likes ice cream, doesn't she?
