Option C is correct.

Capacity Based:Contractors are typically modeled as "Capacity Based Resources" (buckets of work) rather than named individuals, as you usually don't track their specific travel or breaks—you just know they can take "X hours of work per day."

Giving Capacity:You would define the capacityonlyfor the specific 3-week period. Once the capacity records end, the scheduling engine will naturally stop assigning work to them.
