Answer:
E) Market Exchange
Explanation:
Market exchange refers to at least two people or firms trading one good or service for another. In this case, the theater group is trading a free show and other promotional activities (standup comedy nights, and volunteer work) in exchange for higher membership to their group or higher attendance to their shows.
A trade does not necessarily imply a money exchange, it can also include goods or services that provide utility for the other party. For example, an increase in group membership will help the theater group perform better.
