Which of the following is a physiological need?

• A. Water
• B. Social interaction
• C. Acceptance
• D. Independence

Answer: (A)

Physiological needs are the body's most basic survival requirements. Water fits here because it’s essential for life—every cell depends on proper hydration for metabolism, maintaining blood volume, digestion, temperature regulation, and overall organ function. Without enough water, the body can’t operate safely, leading to dehydration and serious health risks. The other options involve psychological or social needs—how we relate to others or our sense of autonomy—rather than the body's immediate biological requirements.
