Which of the following is a physiological need?

• A. The need for social interaction
• B. The need for independence
• C. The need for self-esteem
• D. The need for water

Answer: (D)

Physiological needs are the most basic requirements for life. They are the bodily needs the body must have to function, such as hydration, nutrition, air, sleep, and temperature regulation. Water directly satisfies a fundamental survival need—without enough water, cells can’t operate, blood volume and circulation are affected, and organs can fail—so it is classified as a physiological, or biological, need. The other options relate to social or psychological needs rather than bodily requirements: social interaction touches on belonging and relationships, independence relates to autonomy and control, and self-esteem concerns feelings of worth and achievement. These are important, but they are higher-level needs that come after the physiological needs are met.
