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

The answer is Monopolies.

Reason: The output is inefficient, prices are set high, and consumer is given few choices for selecting the product and services by a monopoly firm. The monopolist exercises a high amount of power as the individual is controlling the whole market.

The rent-seeking means following a practice that manipulates the public and affects economic conditions to increase its own profits. Monopoly firms mainly follow this practice.

So, all the problems related to output, price, limited choice, and rent-seeking are associated with the monopolies.
