Answer: The correct answer is A.
Step-by-step explanation:
An office memo is usually written to remind employees of events, changes or new information made in the company.
This office memo clearly announces a meeting, its date and time as well as the topics that will be covered in it.
Sales numbers and its importance, regular meetings held in the afternoon in mid-week, and getting promoted during business meetings are not the key ideas of the memo, but what the meeting will discuss. This is the business's success (the newest sales items) and achieve the most (appropriate promotions).
