Answer:
Perfectly inelastic
Step-by-step explanation:
In the case where there is a reduction in a price that does not impact the demand done by the consumers so the elasticity of demand with respect to the price would be zero i.e. perfectly inelastic demand
As in the given case there is 4 percent decreased in the price of the product that has no impact on the consumption spenditure so the price elasticity of demand is zero
hence, the same is to be considered
