Final answer:
The demand curve for a good depicts all the information found in the demand schedule, displaying the graphical relationship between quantity demanded and the price, reflecting the law of demand. The correct option is d.
Step-by-step explanation:
The demand curve for a good is a graphical representation of the relationship between the quantity demanded and the price of that good. It is derived from the demand schedule, which is a table showing the quantity of the good that consumers are willing and able to purchase at different prices, assuming ceteris paribus - which means all other factors being equal.
According to the law of demand, there is an inverse relationship between price and quantity demanded; as the price increases, the demand usually decreases, and vice versa, which is depicted by a downward sloping demand curve. Therefore, the correct option for what a demand curve displays is (d) all of the information found in the demand schedule for the good. The demand curve essentially plots the data from the demand schedule in a graph format. This allows for a visual representation of how the quantity demanded changes in response to changes in price.
