What is the Cartesian product of A = {1, 2} and B = {a, b}?(a) {(1, a)

1.	What is the Cartesian product of A = {1, 2} and B = {a, b}?(a) {(1, a), (1, b), (2, a), (b, b)}(b) {(1, 1), (2, 2), (a, a), (b, b)}(c) {(1, a), (2, a), (1, b), (2, b)}(d) {(1, 1), (a, a), (2, a), (1, b)}I got this question in an internship interview.Enquiry is from Sets in portion Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» Correct choice is (C) {(1, a), (2, a), (1, b), (2, b)} The best I can EXPLAIN: A subset R of the Cartesian product A x B is a relation from the SET A to the set B.
