What are physiological needs primarily concerned with?

Physiological needs are fundamentally linked to the basic survival requirements essential for human life. This concept stems from Maslow's hierarchy of needs, where physiological needs sit at the foundational level. These needs encompass the most basic elements necessary for survival, such as food, water, sleep, and shelter. Without meeting these essential needs, individuals cannot focus on higher-level needs such as safety, love, belonging, or self-actualization.

This contrasts with the other options, which focus on social, emotional, or psychological aspects of well-being rather than the physical necessities required for survival. Hence, option B accurately captures the essence of physiological needs as it centers on those critical elements that sustain life.
