The correct answer is: D. was, attempted
The verb “attempt” is used to describe the act of trying to do something. In this case, the question is asking how the person attempted their last question paper. The past tense form of “attempt” is “attempted,” so the correct answer is “was attempted.”
The other options are incorrect because they do not make sense in the context of the question. The verb “do” is not typically used to describe the act of trying to do something. The verb “is” is in the present tense, but the question is asking about the past. The verb “had” is in the past tense, but it is used to describe something that happened before another event in the past.
In conclusion, the correct answer to the question “How was your last question paper attempted?” is “was attempted.”
