The correct answer is D. There is an inverse relationship between price and quantity demanded.
A market demand schedule is a table that shows the relationship between the price of a good and the quantity of that good that consumers are willing and able to buy at each price. The law of demand states that, all other things being equal, the quantity demanded of a good will decrease as the price of the good increases. This is because consumers are generally willing to buy more of a good when it is cheaper, and less of a good when it is more expensive.
Option A is incorrect because it states that as the product’s price falls, consumers buy less of the good. This is the opposite of what the law of demand states.
Option B is incorrect because it states that there is a direct relationship between price and quantity demanded. This is also the opposite of what the law of demand states.
Option C is incorrect because it states that as a product’s price rises, consumers buy less of other goods. This is not necessarily true. Consumers may buy more of other goods if the price of the good in question rises, but this is not always the case.
