Verified step by step guidance1
Understand that a demand curve shows the relationship between the price of a good and the quantity demanded, holding other factors constant.
Recognize that a change in the price of the good itself causes a movement along the demand curve, not a shift of the curve.
Identify factors that cause the entire demand curve to shift, such as changes in consumer income, tastes, prices of related goods, expectations, or the number of buyers.
Analyze each option: a change in consumer income affects consumers' purchasing power and preferences, leading to a shift in demand.
Note that changes in production costs or the number of sellers affect supply, not demand, so they do not shift the demand curve.
