Answer:
The correct answer is letter "A": apparently demand is affected not just by the number of people who use a product but also by the type of person that uses the product.
Explanation:
Demand is defined as the requests of good or services individuals make to satisfy their needs. Usually, demand is related to price while determining the fluctuations in the quantity demanded for a given product. However, price is not the only factor that impacts demand.
Consumer preferences, income, and expectations, advertisements, and the number of consumers in the market also determine the demand for commodities.
