If a consumer’s income increases:   There will be a movement along the demand curve. You Answered  None of these   There will be no change in quantity Correct Answer  There will be a change in demand.

The statement is saying that if a consumer's income increases, there will be a change in demand. This is because the amount of money a consumer has can directly affect their purchasing power.

Here's a step-by-step explanation:

1. A consumer's income increases. This means they now have more money to spend on goods and services.

2. With more money, a consumer has the ability to purchase more goods and services than they could before. This is known as an increase in purchasing power.

3. When a consumer's purchasing power increases, they are more likely to buy more of a good or service. This is especially true for goods and services that are considered normal goods, which are goods that consumers buy more of as their income increases.

4. This increase in the quantity of goods and services that consumers are willing and able to buy at a given price is known as an increase in demand.

5. Therefore, an increase in a consumer's income will cause a change in demand, not just a movement along the demand curve or no change in quantity. The demand curve itself will shift to the right, indicating an increase in demand.
