The answer is

Domain is {2}, Range is {2, 3}

This choice implies we would have a relation with a single domain value of 2 and two range values, 2 and 3. Since there are no other range values for that relation, the domain value of 2 must map to both 2 and 3.

A function must have every domain value mapping to exactly one range value. Therefore, the given relation will never satisfy definition of a function.
