The correct answer is:

C. Both (house, complete mailing address) and (complete mailing address, house) are functions.

Explanation:

A function is a relation in which each element of the domain (x-values) is mapped to one element of the range (y-values).

In the set (house, complete mailing address), the values of "house" would be the domain and the values of "complete mailing address" would be the range. In order to be a function, each value of "house" would be mapped to only one value of "complete mailing address." This is true; each house will have only one complete mailing address. This means it is a function.

In the set (complete mailing address, house), the values of "complete mailing address" would be the domain and the values of "house" would be the range. In order to be a function, each value of "complete mailing address" would be mapped to only one value of "house." This is true; each complete mailing address would go with only one house. This means it is a function.
