A – B, A ∩ B and B – A are mutually disjoint sets or not.

A. True

B. False

I got this question in semester exam.

This intriguing question comes from Operation on Sets-2 in section Sets of Mathematics – Class 11

Correct choice is A. True

For explanation: A – B, A ∩ B and B – A does not have any common region so the intersection of any two of them is null set. So, they are said to be mutually disjoint.
