[A]
On a linear demand curve, all the five forms of elasticity can be depicted’
[B]
If two demand curves are linear and intersecting each other then coefficient of elasticity would be same on different demand curves at the point of intersection.
[C]
If two demand curves are linear, and parallel to each other then at a particular price the coefficient of elasticity would be different on different demand curves
[D]
The price elasticity of demand is expressed in terms of relative not absolute, changes in Price and quantity demanded’
