Answer:
C. They value those goods at least as much as the price charged.
Explanation:
When buyers buy goods in a market they are doing so because they value those goods at least as much as the price charged and obviously prefer the particular good (product) to the other which is being offered by the seller.
This ultimately implies that, when anyone buys a new product, it is simply because they feel the product is going to give them value for the price or amount of money being paid.
