Inefficient output and price, few choices for consumers, and rent seeking are all problems associated with

c. Monopolies.

Explanation:

Because Monopolies have no competition, the main incentive to be efficient is missing. This leads to a situation where Monopolies are not as efficient as they are to be in production as well as price because they will charge a price that does not match the optimal quantity associated with that price.

With no or few competition in the market, consumers will not have a lot of choices on entities to source the good from and there is a problem of Rent seeking with Monopolies as well. Rent seeking for monopolies occurs when they charge people above the price they are to charge if they were in a competitive market. They are therefore making more money than they should at the expense of customers.
