To determine the correct answer for the sentence "Don't forget, we ____ at 9 am on Monday," we need to analyze the options provided.

1. Break Down the Problem

We are looking for the appropriate verb form to complete the sentence, ensuring it correctly indicates a future appointment. The context suggests a scheduled event.

2. Relevant Concepts

In English grammar, we use different tenses to indicate the timing of actions:

• Future Tense: "will have" indicates a future action, but is not typically used with a specified time in this context.
• Present Simple: "have" is often used for scheduled events or timetables.
• Present Continuous: "are having" can also express something planned or arranged, but is often used for ongoing actions.

3. Analysis and Detail

• Option A: "will had a meeting": This option is grammatically incorrect since "will" should be followed by the base form of the verb (have).
• Option B: "have a meeting": This is correct as it indicates a scheduled event.
• Option C: "are having a meeting": While this form could work, it suggests an ongoing action rather than a scheduled event.

4. Verify and Summarize

The most appropriate choice for expressing a scheduled meeting is option B: "have a meeting." Therefore, the completed sentence reads: "Don't forget, we have a meeting at 9 am on Monday."

Final Answer

The correct answer is b. have a meeting.
