Answer:
A. Non-price determinants of demand
Step-by-step explanation:
Substitutes, compliments, expectations, preferences, population, and income are all examples of non-price determinants of demand. These factors influence the demand for a product or service but are not directly related to its price. They can cause the demand curve to shift either to the right (increase in demand) or to the left (decrease in demand). Changes in these determinants can lead to a change in the quantity demanded at any given price.
