(C) We have $A = \{1, 2\}$ and $B = \{3, 4\}$.The Cartesian product $A 	imes B$ is given by $A 	imes B = \{(1, 3), (1, 4), (2, 3), (2, 4)\}$.The number of elements in $A 	imes B$ is $n(A 	imes B) = 4$.$A$ relation from $A$ to $B$ is a subset of $A 	imes B$.The total number of subsets of a set with $n$ elements is $2^n$.Therefore,the number of relations from $A$ to $B$ is $2^4 = 16$.

Let $A = \{1, 2\}$ and $B = \{3, 4\}$. Find the number of relations from $A$ to $B$.
