Answer: (C)

Verified step by step guidance

1. Understand that a demand curve shows the relationship between the price of a good and the quantity demanded, holding other factors constant.
2. Identify that when moving along a demand curve, the price of the good changes, which causes a change in quantity demanded.
3. Recognize that all other determinants of demand (such as consumer income, tastes, prices of related goods, expectations) are held constant during this movement.
4. Note that a change in any of these other determinants would shift the entire demand curve, not cause movement along it.
5. Therefore, the correct interpretation is that when moving along a demand curve, all other determinants of demand except the price of the good are held constant.
