Which of the following is an aggregate?

A. the total production of all goods and services

Explanation:

Aggregate is the term for the sum of things that are separate elements but which together represent the whole, unionized structure.

This is why the separate elements of production, goods, and services which are considered the complete end product of the work are representing aggregate in the group of choices. All other options are either complete sums with no elements or elements that do not form an unionized product or sum.
