Which of the following best describes a "consumer"?

The definition of a "consumer" primarily refers to an individual who engages with goods and services for personal, non-commercial use. This understanding aligns with the notion that a consumer makes purchases or engages in transactions strictly for individual needs or enjoyment, rather than for business or organizational purposes.

The correct choice emphasizes this personal aspect, highlighting that the activities undertaken are solely for one's own use rather than for resale or business operations. In contrast, other options like individuals acting for business purposes or corporations engaging in purchases convey a commercial context that does not align with the typical definition of a consumer.

Therefore, recognizing the distinction between a consumer and other types of purchasers is essential, as it establishes the foundation for consumer protection laws and regulations which primarily focus on individuals engaging in private transactions.
