Question

Mr dutta is ----- the committee. (in /on/ with)

Answer 1

Mr Dutta is in the committee

Thanks for the question

Answer 2

Me. Dutta is ______ the committee ( in/ on/ with)

The correct preposition for the given sentence is: ’in’

This is because Mr. Dutta can’t be on a committee as it sounds wrong.

Same way, Mr.Dutta can be with the committee but that doesn't favor this sentence.

Hence the right answer or the correct preposition for the given sentence is ’in’.

As I indicated that he is a part of the committee.
