Answer:
C. responsiveness of quantity demanded to a change in price
Explanation:
Price elasticity of demand is a measure of the sensitivity of demand for a good or service to changes in the price of that product. We say that the price elasticity of demand is elastic when a percentage change in the price of this good has major impacts on demand. On the contrary, we say that the price elasticity of demand is inelastic when variations in the price of goods have little or no influence on demand.
