The correct answer is A. John is using available and renewable resources.
Explanation:
One of the uses of the economy is to use available resources; this occurs in the case of John because he decides to take advantage of the apples in his orchard, and instead of keeping all the apples for himself, he transforms them into a different product (apple pies) to earn profits. Moreover, because apples replenish naturally in a short time, these show the use of renewable resources that help John to create a sustainable business because it is likely he had apples to produce pies most of the time. According to this, the correct answer is A.
