B. The relation is not a function. Some of the input values are paired with

Step-by-step explanation
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Step 1
Identify the input values and compare with the outputs
as we can see one input is related to TWO outputs, for example
hence, the relation is not a function
