The correct answer is Consumption.

Explanation:

In economics, "consumption" refers to the act of using goods and services, often determined by the buying habits of individuals. It is a fundamental activity in any economy because it drives demand for products.

• Consumer refers to an individual who purchases goods and services for personal use but does not encapsulate the act itself.
• Economy is a broader term that encompasses all economic activities, including production, distribution, and consumption.
• Corporation is a legal entity that engages in business activities but does not specifically relate to the purchase of commodities by consumers.

Thus, "Consumption" is the term that directly refers to the act of using something in an economic context.
