A supply schedule is characterized by this option (if these are the options that you have been given):
it lists supply for a specific good.
The option (it showed the quantity supplied at only 1 price) has to do with invoices. Second option (it showed the factors that could influence supply) is an analysis of a manufacturing process. And the third option (it is sensitive ti change in the cost of labor and parts) is related to the cost of manufacture, not the supply.
