Human behavior is classified into which number of levels or groups?

• A. Five
• B. Six
• C. Three
• D. Four

Answer: (A)

Understanding why people act the way they do often comes down to motivation organized in a layered way. In this common framework, behavior is driven by five levels of needs that sit from the most basic to the most advanced. At the base are physiological needs like food and shelter, followed by safety needs, then social belonging, then esteem, and finally self-actualization at the top. A person tends to focus on satisfying the lowest unmet need, and as each level is fulfilled, attention and actions gradually shift to the next level. This five-level structure is a widely taught, practical way to explain how motivation guides behavior across different situations. So the number of levels is five.
