The Correct Option is B

Solution and Explanation

Given the set A = {p, q}, we want to find the number of subsets of A.

The number of subsets of a set with n elements is given by 2n.

Here, A has 2 elements (n = 2), so the number of subsets is 22 = 4.

These subsets are:

  1. The empty set: ∅
  2. {p}
  3. {q}
  4. {p, q}

Therefore, the correct answer is (2) 4.
