Final answer:
The computer market in recent years has seen many more computers sell at much lower prices. The most likely explanation for this outcome is a fall in demand. Option A
Step-by-step explanation:
The correct answer is b) A fall in demand. When more computers are selling at much lower prices, it indicates a decrease in the demand for computers. This means that fewer people are willing to buy computers at the current prices.
A fall in demand would result in a leftward (or upward) shift in the demand curve. This shift would lead to a decrease in both the quantity demanded and the equilibrium price of computers in the market.
To visually represent this on a demand and supply diagram, you would shift the demand curve to the left, resulting in a new equilibrium point with a lower price and quantity demanded. Option A
