# If A is a proper subset of B, then A ∩ B =

A. A

B. B

C. Φ

D. A ∪ B

Answer :

Given, A is a proper subset of B

Let us consider two set as A is a proper subset of B

A = {9, 8, 7, 6, 5, 4} B = {1, 2, 3, 4, 5, 6, 7, 8, 9}

A ∩ B means we have write all the common elements of both the sets.

A ∩ B = {9, 8, 7, 6, 5, 4} ∩ {1, 2, 3, 4, 5, 6, 7, 8, 9}

= {4, 5, 6, 7, 8, 9}

The resultant set is same as A

Option A is the correct answer.
