Answer:
The correct answer is option b.
Explanation:
A steep demand curve implies that the demand is relatively inelastic. In other words, a significant change in price will cause a small change in the quantity demanded.
A flatter demand curve, on the contrary, implies that a small change in price will cause a greater change in quantity demanded. In other words, demand is relatively elastic.
A change in price will not cause demand to change if the elasticity of demand is perfectly inelastic or when the demand curve is a vertical line.
A change in demand will be equal to the change in price if demand is unitary elastic.
