Which of the following enables people to consume a variety of goods and services?

Exchange enables people to consume a variety of goods and services. Exchange refers to the process of trading goods or services between two or more parties. It allows people to obtain goods and services that they may not be able to produce themselves or do not have access to. By exchanging goods and services with others, individuals can consume a wider variety of goods and services beyond what they are able to produce on their own. This creates a more diverse and efficient economy, as it enables individuals to specialize in producing certain goods or services, while still having access to a wide range of other goods and services through exchange.
