Which of the following indicates a more elastic demand curve?

A flatter demand curve indicates a more elastic demand. This is because elasticity measures how responsive the quantity demanded of a good is to changes in its price. When the demand curve is flatter, small changes in price lead to large changes in the quantity demanded. For example, if the price drops slightly, consumers are significantly more likely to purchase the good, showing a high sensitivity to price changes.

In contrast, a steeper demand curve signifies inelastic demand, where changes in price have a relatively small effect on the quantity demanded. A vertical demand line represents perfectly inelastic demand, indicating that quantity demanded does not change regardless of price changes. A curved line can represent varying elasticity at different points, but without specific information about its slope, it does not indicate a consistent level of elasticity like a flat curve does. Therefore, the flatness of the curve directly correlates with the greater elasticity of demand.
