Let A = {circle, square, triangle} and let B = {0, 1}. Find A X B.

A) {circle, square, triangle, 0, 1}
B) { }
C) {(circle, 0), (circle, 1), (square, 0), (square, 1), (triangle, 0), (triangle, 1)}
D) {0, 1}

I'm stuck on two answers, A and C, so which one would be correct?

Hint: Similar example:

If A = {1, 2, 3} and B = {10, 11, 12}, then


A X B = {(1,10), (1,11), (1,12), (2,10), (2,11), (2,12), (3,10), (3,11), (3,12)}
