What can be considered a primary need in the psychological hierarchy?

The primary needs in the psychological hierarchy, often illustrated by Maslow's hierarchy of needs, refer to the most fundamental necessities for human survival and well-being. These needs include air, water, food, and shelter, as they are essential for physical survival. Without meeting these basic physiological needs, individuals cannot focus on higher-level needs such as safety, social belonging, esteem, or self-actualization.

In contrast, health and property, while important, are not as fundamental to immediate survival as the basic physiological needs. Employment and resources are also significant but typically become priorities only after primary needs are met. Recognition and self-esteem pertain to higher psychological needs that emerge only after basic and safety needs are secure. Thus, air, water, food, and shelter are the cornerstone of the hierarchy, making them the correct answer.
