General KnowledgeIndian Economy
- AChange in its price
- BChange in price of the other commodities
- CChange in income of the consumer
- DChange in tastes and preferences of consumers
Explanation
A movement along a fixed demand curve is caused solely by a change in the commodity's own price, with all other factors held constant (ceteris paribus). Changes in consumer income, tastes and preferences, or the prices of other commodities shift the entire demand curve instead of moving along it. The price change is therefore the correct answer.
