In the context of a small business, price is best defined as
a. the cost to the owner of doing business.
b. what an employer pays an employee.
c. the amount of money a buyer will pay for a good.
d. the cost of all licenses and permits.

In the context of a small business, price is best defined as A - the cost of the owner of doing business. 

I think this would be the correct answer because small businesses often rely only on the owner who has to provide the goods and he then sells them. The amount he spends on providing them is reflected in the price.
