Assume the demand curve for a good is perfectly inelastic and the production of each unit of this good generates external costs. A profit-maximizing firm producing the good in an unregulated free market will (A)generate deadweight loss because marginal social cost is greater than marginal private cost. (B) generate deadweight loss only if marginal costs are constant
(C) not generate deadweight loss because the equilibrium quantity is socially optimal (D) not generate deadweight loss unless marginal costs are constant (E) not generate deadweight loss unless fixed not costs are zero
