He is married . . . . . . . . Maria. A. about B. to C. of D. in

The correct answer is B. to.

The preposition “to” is used to indicate a relationship between two people, such as marriage,

engagement, or friendship. In this case, the speaker is saying that the man is married to Maria.

The other options are incorrect because they do not indicate a relationship between two people. The preposition “about” is used to indicate

a topic of discussion, the preposition “of” is used to indicate possession, and the preposition “in” is used to indicate a location.

Here are some examples of how the preposition “to” is used to indicate a relationship between two people:

• He is married to Maria.
• I am engaged to John.
• We are friends.
• They are enemies.
