E. All of the above

Explanation:

A. The price elasticity of demand can vary from person to person because different individuals may have different responses to a change in price. For example, a wealthy person might not reduce their consumption of a good if its price increases, while a less wealthy person might.

B. The number of substitutes can affect the price elasticity of demand. If there are many substitutes for a good, then its demand is likely to be elastic because consumers can easily switch to another good if the price increases. On the other hand, if there are few substitutes, then its demand is likely to be inelastic.

C. The price elasticity of demand can change over time. For example, in the short run, consumers might not be able to reduce their consumption of a good if its price increases because they need time to find substitutes. But in the long run, they might be able to reduce their consumption, making the demand more elastic.

D. The proportion of income the good requires in order to be purchased can affect the price elasticity of demand. If a good requires a large proportion of a person's income, then its demand is likely to be elastic because a price increase would significantly affect the person's ability to afford the good. On the other hand, if a good requires a small proportion of a person's income, then its demand is likely to be inelastic.
