Respuesta :

Answer:

(C) perfectly inelastic.

Explanation:

Elasticity of demand measures the responsiveness of quantity demanded to changes in price.

Demand is perfectly inelastic if a change in price has no effect on quantity demanded. Quantity demanded remains unchanged no matter the change in price.

Water is assumed to be a necessity so demand would not change no matter the change in price.

Demand is inelastic when a change in price has little or no effect on quantity demanded.

Demand is elastic when a change in price has a greater effect on the quantity demanded.

Demand is unitary elastic when a change in price has an equal erfect on quantity demanded.
