Which of the following best characterizes a consumer?

A consumer is best characterized as a person who purchases goods or services primarily for personal use rather than for resale or commercial purposes. This definition highlights the role of the consumer in the economy, focusing on their engagement in buying products that fulfill their own needs or desires.

In contrast, the other options refer to different market roles. The first choice points to a business entity that focuses on selling products, which reflects a seller rather than a buyer. The second choice refers to someone who purchases goods specifically for resale, indicating a wholesaler or retailer role, which does not align with the typical definition of a consumer. The last option describes an individual engaged in wholesaling, further straying away from the concept of personal consumption.

Therefore, the focus on personal use in defining a consumer underscores the core characteristics of this role in economic transactions, making it the most accurate characterization.
