I don’t see any point in arriving early . . . . . . . . the theatre if the show doesn’t start until 9 o’clock? A. in B. at C. of D. to

The correct answer is at.

The preposition at is used to indicate a specific time or place. In this case, the speaker is saying that there is no point in arriving at the theater before 9 o’clock, which is when the show starts.

The other prepositions would not make sense in this context. In is used to indicate a general location or period of time. Of is used to indicate possession or a part of something. To is used to indicate a destination or purpose.

Here are some examples of how the other prepositions could be used:

• I arrived in the theater at 8:30.
• The show is of great interest to me.
• I went to the theater to see the show.
