A single-price monopoly

A. eliminates all the consumer surplus.

B. charges all consumers the lowest price that they want to pay for each unit purchased.

C. produces less output than it would if it could discriminate.

D. creates a smaller deadweight loss than it would if it could discriminate.

Answer: C

A single-price monopolist produces less than it would if it could discriminate because the whole point of a monopoly is to transfer consumer surplus to producer surplus. If you can price discriminate, you can better transfer that consumer surplus and thus earn profits selling to those you wouldn't have if you charged a single price. Perfect price discrimination for example gets rid of all consumer surplus. The better a monopolist can discriminate, the more output they will produce.
