Let A and B be finite non-empty sets with the number of elements in A = m and number of elements in B = n. Let m > n. If for some integer k ≥1, the number of non-empty subsets of A = 2^k + the number of non-empty subsets of B, then which one of the following is correct?

m = n + 2

m = n + 1

m = n + p for some odd prime number p
