Answer: {(1,3),(1,4),(2,3),(2,4)}
Explanation:
Step -1: Define the Cartesian product.
Cartesian product: If A and B are two non empty sets, then
Cartesian product A×B is set of all ordered pairs (a,b) such that a∈A and b∈B.
Step -2: Find the Cartesian product of given sets.
We have given,
A={1,2} and B={3,4}
So, A×B={(1,3),(1,4),(2,3),(2,4)}
Hence, option A. {(1,3),(1,4),(2,3),(2,4)} is correct answer.
