Sum of the labor supplied by everyone in the economy (D)

Explanation:

The aggregate supply of labor is the sum of the labor supplied by everyone in the economy usually at a place of work/production.

The individual labor supply in an economy makes up the Aggregate supply of labor because when all the labor efforts of the individual labors are pooled together the production of goods and services will be more efficient rather than when each individual performs disjointed production operations.
