A movement along the same demand curve of a good is caused by a change in which of the following?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Price of the good itself
A demand curve shows how much is bought at each price of the good itself, with other things unchanged. So a change in its own price moves the consumer to another point on the same curve.
Income, prices of related goods and tastes are the ‘other things’. A change in any of them shifts the curve instead.
NCERT (2026-27): “2.4.6 Movements along the Demand Curve and Shifts in the Demand Curve As it has been noted earlier, the amount of a good that the consumer chooses depends on the price of the good, the prices of other goods, income of the consumer and her tastes and preferences. The demand function is a relation between the amount of the good and its price when other things remain unchanged. The demand curve is a graphical representation of the demand function. At higher prices, the demand is less, and at lower prices, the demand is more. Thus, any change in the price leads to movements along the demand curve. On the other hand, changes in any of the other things lead to a shift in the demand curve. …” |
