Question

Fill in the blank with the most appropriate word.

There have been a lot of complaints _____ your behavior.

• A. In
• B. On
• C. Out of
• D. About

Answer 1

Answer: (D)

About

Preposition 'about' means 'in connection with.' As this sentence seeks to establish connection between 'complaints' and 'behaviour,' 'about' would be used here. So, Option D is the correct answer as it points to the reference point, which is ‘behavior’. Options A, B and C cannot be used here as they would not act as pointer and render the sentence meaningless.
