The law of demand states that: a. a higher price will lead to increased sales. b. consumers have unlimited demands for a good. c. the price can never be too high for some consumers. d. quantity demanded will vary inversely with the price of the good.

d. quantity demanded will vary inversely with the price of the good.

Explanation:

The law of demand states that when the price of a product increases, the quantity demanded decreases when everything else remains constant as people are less willing to purchase a product when the price is higher. This means that the price and the quantity demanded are inversely related as when one variable increases the other one decreases. According to this, the answer is that the law of demand states that quantity demanded will vary inversely with the price of the good.

The other answers are not right because the law of demand states that the price and the quantity demanded of a good are inversely related, it doesn't refer to the price and sales, consumers don't have unlimited demands for a good as it is affected by the price and the price can be too high for some consumers as when the price increases, the quantity demanded decreases.

answer: i'd say the answer is d because the information system is the human already doing the activity.
