Question : Statement 1: The price elasticity of demand for a product is zero when quantity demanded does not change with a change in price.
Statement 2: Zero price elasticity indicates a vertical demand curve.
Option 1: Both statements are true.
Option 2: Both statements are false.
Option 3: Statement 1 is true, and statement 2 is false.
Option 4: Statement 1 is false, and statement 2 is true.
Correct Answer: Statement 1 is true, and statement 2 is false.
Solution : The correct answer is (C) Statement 1 is true, and statement 2 is false.
Statement 1 is true. When the quantity demanded does not change with a change in price, the price elasticity of demand is indeed zero. This situation represents perfectly inelastic demand.
Statement 2 is false. Zero price elasticity does not indicate a vertical demand curve. A vertical demand curve represents perfectly inelastic demand, where any change in price does not result in a change in quantity demanded. In this case, the price elasticity of demand is infinite, not zero.
Therefore, the correct answer is C) Statement 1 is true, and statement 2 is false.
