Question
A horizontal straight line demand curve shows zero elasticity of demand.
✓
Answer
False. A horizontal straight line demand curve parallel to $X-$axis shows infinite elasticity of demand $(E_d = \infty )$. Because, slope of a horizontal straight line $= 0.$
So that, $E_d=\frac{1}{\text { Slope of demand curve }} \times \frac{P}{Q}$
$=\frac{1}{0} \times \frac{P}{Q}=\infty$
