Answer
Brief Explanations:
Deadweight loss is the loss of economic efficiency that occurs when the equilibrium outcome is not achieved. A per - unit tax creates a wedge between the price consumers pay and the price producers receive. This leads to a reduction in the quantity traded compared to the free - market equilibrium. Social surplus is the sum of consumer and producer surplus. The reduction in quantity due to the per - unit tax results in a loss in social surplus, which is the deadweight loss.
Answer:
A. A per unit tax results in a loss in social surplus.
