Question

Fill in the blank with an appropriate preposition:

There is a ban ____ mobile phones in Samir's school.

• A. with
• B. on
• C. for
• D. in

Answer 1

Answer: (B)

on

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Option B)on is correct as it indicates involvement. The other options are wrong as with, for, and in indicate inclusion, a purpose, and the inside of something respectively. These uses don't fit in the given question. The correct answer is B)on.
