Choice (a) is correct.
We have, n(A) = m and n(B) = n
n(A × B) =n (A).n(B) =mn
Number of subsets of A × B = 2ᵐⁿ
Number of non-empty subsets of A × B = 2ᵐⁿ -1
Number of non-empty relation from A to B = 2ᵐⁿ -1
This question related to Chapter 2 maths Class 11th NCERT. From the Chapter 2: Relations and Functions. Give answer according to your understanding.
