Both industries experience the same rise in price from P₀ to P₁. Which statement is most likely to be correct?
Industry X has more price-elastic supply, so its quantity supplied changes proportionately more.
Industry Y has more price-elastic supply because its supply curve is steeper.
Both industries have unitary price elasticity of supply because the price change is the same.
Industry X has perfectly inelastic supply because its curve is not vertical.
