Mr. Michael is . . . . . . . . He’ll be back soon. A. of B. over C. away D. against

The correct answer is C. away.

The word “away” means “not here; at a distance.” In this context, it is used to indicate that Mr. Michael is not currently present, but that he will be back soon.

The other options are incorrect because they do not convey the same meaning. The word “of” means “belonging to” or “related to.” The word “over” means “above” or “on top of.” The word “against” means “in opposition to.”

Here are some examples of how the word “away” can be used in other sentences:

• The cat ran away.
• I’m going away for the weekend.
• The wind blew the leaves away.
