The correct answer is: B. Minutes of the last meeting are to be completed.
The other options are incorrect because they do not use the correct verb tense. The verb “to complete” is in the infinitive form, which is used to express a future action. In this case, the action is the completion of the minutes of the last meeting. The infinitive form is also used to express a command or request. In this case, the command or request is for the minutes to be completed.
A. The last meeting’s minutes are completed.
This sentence is in the past tense, which is incorrect because the action has not yet been completed.
C. The meeting’s last minutes are completed.
This sentence is also in the past tense, which is incorrect because the action has not yet been completed.
D. The completed minutes of last meeting is to be tabled.
This sentence is in the singular form, which is incorrect because the minutes are a plural noun. The sentence should be “The completed minutes of the last meeting are to be tabled.”
In conclusion, the correct answer is: B. Minutes of the last meeting are to be completed.
