Answer:
A. elastic.
Explanation:
Elasticity of demand measures the responsiveness of quantity demanded to changes in price.
Demand is elastic when a change in price leads to a change in quantity demanded. The coefficient of elasticity for elastic demand is usually greater than one.
Demand is inelastic when a change in price has no effect on quantity demanded.
The absolute value of the coefficient of elasticity for inelastic demand is usually less than 1.
Demand is unitary when a change in price leads to an equal proportional change in quantity demanded.
The absolute value of the coefficient of elasticity for unitary demand is usually equal to one .
