Answer:
The correct answer is options I, II and III.
Step-by-step explanation:
The imposition of taxes causes buyers to consume less as their disposable income decreases. Because of the reduction in demand the producers will supply less.
If the elasticities of demand and supply are higher, the deadweight loss will be higher as well.
As the tax rate is increased the deadweight loss will increase as well.
As tax grows larger, the demand and supply increases, this reduces the tax base decreases causing revenue to decrease.
