b.

knowledge . . opportunity
c.

willingness . . ability
d.

strength . . commitment

The correct answer is C.

The supply function represents the quantity of a certain good or service that producers are willing to offer in the market at different price levels. For example, a producer is not able to sell  a product if the price that he can charge in the market is smaller than the costs he had beared to manufacture it.

The law of supply states that there is a direct relationship between price and quantity supplied (ceteris paribus, hence, given that the rest remains equal).Therefore, when the price charged increases, the amount that producers are willing to supply increases as well.

Option C, willingness and ability, is the correct answer.

Explanation:

In the context of economics, supply is the amount of stock that firms, producers, workers, providers of commercial assets etc are willing and ready to present to the marketplace. According to the law of supply, there is a direct relationship between the price of the commodity that the suppliers are willing to sell. In this way, the willingness and ability of the supplier is a must. Therefore, option C will be the right answer.
