To determine
Elasticity of a linear downward sloping demand curve.

Option (d)

Linear downward sloping demand curve has a constant slope but a varying elasticity of demand. It varies between different pairs of points along a linear demand curve. The lower the price, the greater the quantity demanded and vice-versa. Thus it is elastic at some points and inelastic in other points. So optionâ€˜dâ€™ is correct.

Option (a)

Demand curve is inelastic when it is a steeper curve...
