Answer:
(C). the quantity demanded of a product is inversely related to its price.
Explanation:
According to the law of demand, when the price of a product is high, the quantity of that product that will be demanded will be low, because customers won't want to pay so much to get the product.
Similarly, when the price of the product drops, the the demand for it will increase.
Therefore the quantity of a product demanded is inversely related to its price.
