Dr. Blake is retiring at the end of the month. There will be an unoccupied office upon his departure, and it is big in size. Because every other office is occupied, we should convert Dr. Blake's office into a lounge. It is absolutely essential that this issue is discussed at the next staff meeting a. We need to discuss this essential issue at the meeting. b. We need to discuss all of this at the next meeting

A

Explanation:

As we prepare an email to send to a whole team which could include many people and areas, including higher-ups, is imperative to be clear and to the point. All the sentences in the question point to a single issue: the repurpose of a single big office into something else. There are not many issues, only one. Therefore, the best way to communicate that in a corporate email is alternative A, where it is clearly stated that it is an essential issue, and not the informal phrase “all of this”.  

The correct answer is B. We need to discuss all of this at the next meeting.

Explanation:

I just did the test and this was the correct choice.
