What did you think . . . . . . . . the film? I did not like it much. A. in B. of C. about D. on

The correct answer is C. about.

The preposition “about” is used to talk about something in general. In this case, the speaker is asking the listener for their opinion on the film in general.

The other prepositions could also be used in this sentence, but they would have different meanings.

• The preposition “in” is used to talk about something that is inside something else. For example, “I thought the film was in good taste.”
• The preposition “of” is used to talk about something that is related to something else. For example, “I thought the film was of high quality.”
• The preposition “on” is used to talk about something that is located on something else. For example, “I thought the film was on a serious topic.”
