Step-by-step explanation:
We have been given a set. We are asked to choose the correct option about the given set.
We know that a set represents a relation, when each x value corresponds to a y-value. In a relation one x-coordinate can have more than one y-values.
We know that a set represents a function, where each x-value corresponds to exactly one y-value.
Two different value can have same y-value to be a function.
We can see that each value of x corresponds to exactly one y-value. The value of y is 2 for all value of x, therefore, all points lie on a horizontal line .
Therefore, our given set a function.
