In Maslow's hierarchy of needs, which category is considered foundational?

• A. Safety and security
• B. Physiological needs
• C. Love and belonging
• D. Self-actualization

Answer: (B)

Maslow's hierarchy begins with needs essential to survival. Physiological needs form the base of the pyramid, including air, water, food, shelter, warmth, sleep, and sex. Because these basic biological requirements must be met for a person to survive, they take priority over all other needs. Only after they are satisfied can a person focus on safety and security, then love and belonging, then esteem, and finally self-actualization. In practice, this means addressing basic life-sustaining needs first—nutrition, hydration, temperature regulation, rest, and a safe environment—before tackling higher-level psychosocial goals. That’s why physiological needs are considered foundational.
