Answer:

The correct answer is option D.

Step-by-step explanation:

The price elasticity of demand measures the degree of responsiveness of quantity demanded to a change in price. It is the ratio of proportionate change in quantity demanded and proportionate change in price.

The slope of the demand curve is the ratio of the percentage change in the price and percentage change in quantity. It is related to the price elasticity but is not the same.
