• A. The product becomes less popular due to a change in tastes.
• B. The price of the product rises.
• C. Consumers’ incomes rise and the product is a normal good.
• D. The price of a complement to the product rises.

Answer: (C)

Verified step by step guidance

1. Understand that a demand curve shifts to the right (increases) when consumers are willing to buy more of the product at every price level.
2. Recognize that a change in tastes making the product less popular would decrease demand, shifting the curve to the left, so this does not cause an increase in demand.
3. Know that a rise in the product's own price causes a movement along the demand curve (a decrease in quantity demanded), not a shift in demand.
4. Identify that if consumers' incomes rise and the product is a normal good, then demand increases because consumers can afford to buy more, shifting the demand curve to the right.
5. Understand that if the price of a complement rises, the demand for the product typically decreases because the combined cost of using both goods is higher, shifting demand to the left.
