Which of the following is classified as a need?

The classification of needs vs. wants is a fundamental concept in economics. A need is something that is essential for survival, while a want is something that is desired but not necessary. The correct choice—food and water—are basic human necessities. These items are critical for sustaining life and maintaining health. Without access to food and water, individuals cannot survive, making them fundamental elements of human requirements.

In contrast, luxury items, entertainment services, and fashion clothing can all be classified as wants rather than needs. While they may enhance quality of life or provide comfort, they are not essential for survival. Therefore, in the context of economic decision-making and resource allocation, food and water represent the most basic and critical needs that everyone requires to live.
