Hello!
The answer is: C. It shows the supply for a product at various prices.
Why?
Supply schedules are used to show the quantity of services or goods that will be offered at various prices for a specific period of time.
For example, we can use a supply schedule to show how many hours will a worker do his work at a determinate price, he could work 2 hours at 35$ the next hour at 40$ and the next five hours at 45$ depending on the work that he is going to do.
Have a nice day!
