Solution
The question is asking for the number of binary relations from set A to set B that are functions.
In a function from A to B, each element of A must be related to exactly one element of B.
Since A has 3 elements and B has 4 elements, each element of A has 4 choices in B.
Therefore, the total number of functions from A to B is 4^3 = 64.
However, none of the options provided in the question match this answer. It seems like there might be a mistake in the question or the provided options.
