Which of the following is NOT a function of the physiological needs according to Maslow's hierarchy?

According to Maslow's hierarchy of needs, physiological needs are the most basic human requirements essential for survival. These needs include air, food, water, shelter, and other factors necessary for physical well-being.

Breathing, nourishment, and shelter are all fundamental elements of physiological needs, as they are directly related to maintaining the body's health and functionality. These aspects must be met first in order for individuals to pursue higher-level psychological and social needs.

Relationship building, however, falls under the category of social needs, which come after physiological needs in Maslow's hierarchy. Social needs involve the desire for interpersonal relationships and connections, which are secondary to the immediate requirements for survival. Therefore, relationship building is not a function of physiological needs, making it the correct choice in this context.
