Answer:
A) elastic.
Explanation:
Demand elasticity is a microeconomic concept that aims to measure the sensitivity of demand in the face of price changes. When price goes up and demand goes down a lot, demand is said to be price elastic. When price rises and demand does not change significantly, demand is said to be inelastic to price. Therefore, if the rise in gasoline prices causes a decrease in the entrepreneur's revenue, we say that the demand for gasoline is elastic.
