The major factors affecting demand

The correct answer is D. All of these.

The demand for a good or service is the amount of that good or service that consumers are willing and able to purchase at various prices during a given period of time. The law of demand states that, all other things being equal, the quantity demanded of a good or service will decrease as the price of that good or service increases.

There are a number of factors that can affect the demand for a good or service, including:

• The price of the good or service: As the price of a good or service increases, consumers will generally demand less of it. This is because consumers have a limited amount of money to spend, and they will want to get the most value for their money.
• The income level of consumers: As consumers’ incomes increase, they will generally demand more goods and services. This is because they have more money to spend, and they can afford to purchase more things.
• The prices of other goods and services: The demand for a good or service can be affected by the prices of other goods and services. For example, if the price of a substitute good decreases, the demand for the original good will decrease. This is because consumers will now be able to get the same satisfaction from the substitute good at a lower price.
• The tastes and preferences of consumers: The demand for a good or service can also be affected by the tastes and preferences of consumers. If consumers’ tastes change in favor of a good or service, the demand for that good or service will increase.
• The number of consumers in the market: The demand for a good or service will also depend on the number of consumers in the market. If the population increases, the demand for most goods and services will increase.
• The expected future price of the good or service: The demand for a good or service can also be affected by the expected future price of that good or service. If consumers expect the price of a good or service to increase in the future, they may demand more of that good or service now in order to avoid paying a higher price later.

These are just some of the factors that can affect the demand for a good or service. The demand for a good or service is a complex issue, and there are many factors that can influence it.
