Answer:
B) the consumers generally pay the majority of the tax.
Step-by-step explanation:
Unit Excise is an indirect tax ; whose incidence & impact lie on different people and the burden can be shifted among buyers & sellers.
The economic participant (buyers / sellers) having more inelastic market force (demand / supply) shares more burden of the tax. More burden of Indirect tax: lies on buyers if demand is more inelastic (less responsive to price) , lies on sellers if supply is more inelastic (less responsive to price).
So, if Unit Excise tax is placed on a good for which demand is very unresponsive to price change (inelastic) : Consumers (buyers) generally pay the majority of the tax.
