Question

Quizplus · Accepted Answer

A movement along a demand curve indicates a change in quantity demanded, which is caused by a change in price (the only factor that affects quantity demanded). Therefore, the answer is not A, B, or C. A change in supply would affect the market equilibrium price, which would then cause a movement along the demand curve as quantity demanded changes in response to the new price. So, the correct answer is D.
