Correct answer: A
The correct option is A: open.
Detailed Explanation
Grammatical Rule: In English, when using the auxiliary verb "did" to form a question in the simple past tense, the main verb that follows must be in its base form (the bare infinitive).
Application: Because the auxiliary verb "did" is already in the past tense, the main verb "open" should remain in its base form. Using a past tense or perfect tense verb (like "opened" or "had opened") after "did" is grammatically incorrect.
