To choose the correct option for the sentence "By 9 O'clock, we _________________ our homework," we need to analyze the context provided by the time reference "by 9 O'clock." This phrase suggests a future time frame where an action will be completed.

Analysis of the Options:

1. have finished - This form is the present perfect tense, indicating an action that was completed at some undefined time in the past, which doesn't fit the future context.

2. are finished - This is the present tense, which also doesn’t align with the future completion implied by "by 9 O'clock."

3. will have finished - This is the future perfect tense and indicates that the action will be completed by a specific time in the future, which fits perfectly here.

4. will have finish - This is grammatically incorrect; the correct form is "will have finished."

Final Answer

The correct option is will have finished. Hence, the complete sentence should be: "By 9 O'clock, we will have finished our homework."
