Which statement is true?

A) A vertical demand curve has zero elasticity.
B) A horizontal demand curve has zero elasticity.
C) Both vertical and horizontal demand curves have zero elasticity.
D) Neither vertical nor horizontal demand curves have zero elasticity.

Vertical Demand Curve

A vertical demand curve is a theoretical representation where the quantity demanded is completely insensitive to price changes, indicating that consumers are willing to buy the same amount regardless of the price.

Elasticity

A measure of how much the quantity demanded or supplied of a good or service changes in response to a change in price, income, or other factors.
