Board . . . . . not . . . . . . this question in the previous exam.

Solution (By Examveda Team)

Definition:
The sentence is in the past tense because it refers to the "previous exam." When forming negative sentences in the past simple tense, we use "did not" + base form of the verb. Correct Answer:
The correct option is Option A: did, ask. Explanation:
- The subject of the sentence is "Board," which is singular, but in past simple negative sentences, we use "did" for all subjects.
- The correct structure for a negative sentence in past simple is: Subject + did not + base form of the verb.
- "Ask" is used in its base form because "did" already indicates the past tense.
- Therefore, the correct sentence is: Board did not ask this question in the previous exam. Why Other Options Are Incorrect:
- Option B: was, ask → Incorrect because "was" is used for passive voice, and "ask" in its base form does not fit after "was." The correct passive form would be "was asked."
- Option C: does, ask → Incorrect because "does" is used for present tense, while the sentence refers to the past.
- Option D: will, ask → Incorrect because "will" is used for future tense, but the sentence talks about a past event.
Final Answer: Option A: did, ask.
