The new store opens . . . . . . . . business in March. A. for B. in C. about D. of

The correct answer is in.

The word “in” is used to indicate a specific time or period of time. In this case, the store is opening in the month of March.

The other options are not as accurate. The word “for” is used to indicate a purpose or reason. The word “about” is used to indicate a topic or subject. The word “of” is used to indicate possession or a part of something.

Here are some examples of how the other options could be used in a sentence:

• The store is open for business.
• The store is about to open.
• The store is a part of the mall.
