Quizplus · Accepted Answer

A change in the quantity demanded refers to a movement along a given demand curve in response to a change in price (option D). However, a change in any of the other factors that influence demand, such as income, consumer preferences, or the availability of substitute goods, would shift the entire demand curve either to the left or the right (option A) and result in a change in the quantity demanded at any given price. Therefore, a change in the quantity demanded can be both a movement along a given demand curve and a shift in the demand curve itself (which is why option E is the correct answer).
