Mom is setting the table with the good china.
Choose the clause that best completes the sentence above.
A. My sister Angela won her school's spelling bee so
B. Because her boss is coming over for dinner
C. We are having special guests over for dinner
D. My family and I are celebrating Dad's promotion

The correct answer is C: We are having special guests over for dinner.

Explanation:

This could be the correct option, as people usually set the table with the high-quality porcelain plates when they are having special guests over or dinner. In our example, that possibility is listed under the letter C, so we should take into account that speaker's mother expects someone who is really important or her, that is, her special guests.

She could also have her boss coming over for a dinner, but that case is not so common, except if they were friends out of work, but then she probably wouldn't set the table with the good china.
