    The correct option is Sets A and B only

    Step-by-step explanation:

    A relation in a set is said to be function, if every first element of an ordered pair in a set is related with unique element of second element.

    No, two distinct second element of an ordered pair, has same first element.

    For Set A:

    Every First element of set A has unique second element. So, it is a function.

    For Set B:

    Every First element of set B has unique second element and no two distinct Second element of set B, has same first element. So, it is a function.

    Thus the correct option is Sets A and B only.
