Map Properties 11 Consider the following set of ordered pairs of the elements of a set A = {1,2,3,4} of numbers and a set B = {a, b, c, d} of letters. {(1, a),(2,b), (3, a),(4, d)} Select all options true of this set. This is not a map from A to B. This is a map from A to B and is onto. This is a map from A to B and is one-to-one. This is a map from A to B and is neither one-to-one nor onto.
