Which of the following means "the general willingness of businesses to make and sell a specific quantity of a product at various prices"? supply demand quantity supplied quantity demanded

Answer: Supply

Explanation:

Supply is known to be the amount of goods (products) and services which a producer is willing and able to supply to the market at various prices over a specified period of time. Thus, producers tend to produce and supply more goods and services as prices go higher in order to get more profits and revenue.

I mean, from the question, I can gather that the answer is supply. I have no idea about the "supply demand quantity supplied quantity demanded" thing.
