Final answer:
The correct answer is D) Increases.
Step-by-step explanation:
The law of supply states that when the price of a product increases, the quantity supplied of the product will also increase, assuming all other variables are held constant.
This relationship can be explained by the fact that producers are more willing and able to supply a larger quantity of a product when they can earn a higher price for it. For example, if the price of apples increases, apple farmers may be motivated to grow more apples to take advantage of the higher profits.
