The correct answers are Did you take my chocolate donut yesterday?, Were you in the kitchen this morning?, and Do you have a donut in your pocket right now?.

"Did you take..." correctly uses the past auxiliary "did" with the base verb "take".

"Were you..." correctly uses the past tense of "be" for the pronoun "you".

"Do you have..." correctly uses the present auxiliary "do" with the main verb "have".

Incorrect Options:

"Was you" is incorrect because "you" always takes "were" in the past tense.

"Did you took" is incorrect because after the auxiliary "did", we must use the base form of the verb ("take"), not the past tense.
