What is included in physiological needs according to Maslow's Hierarchy?

In Maslow's Hierarchy of Needs, physiological needs represent the most fundamental requirements for human survival. These needs include essentials such as food, water, shelter, and sex, as they are necessary for maintaining the body's biological functions and ensuring survival. This foundational level forms the base of the hierarchy, as individuals must satisfy these basic needs before they can pursue higher-level needs such as safety, social belonging, esteem, and self-actualization.

The other options pertain to higher levels of needs in Maslow's framework. Approval and recognition relate to esteem needs, which focus on self-esteem and the respect of others. Emotional security and social interactions fall under the category of belongingness and love needs, emphasizing relationships and a sense of connection with others. Lastly, cognitive challenges and intellectual growth are associated with self-actualization needs, which involve personal development and realizing one’s full potential. Therefore, the emphasis on food, sex, and shelter aligns directly with the physiological needs, confirming why this response is the correct interpretation of Maslow's model.
