Which of the following is a physiological need?

Physiological needs are the fundamental requirements for human survival and are located at the base of Maslow's hierarchy of needs. These needs include essential elements necessary for maintaining life, such as food, water, air, shelter, and sleep. The option that includes food and water directly addresses these vital requirements for sustenance and health.

Understanding physiological needs is crucial in the context of safety supervision because a safe working environment must ensure that these basic needs are met. Without fulfilling physiological needs, individuals cannot focus effectively on higher-level needs such as belonging, esteem, or personal achievement. This prioritization is essential for creating a healthy and functional workforce in naval operations, where physical and mental well-being plays a critical role in overall performance and safety.
