Explanation:

Let’s break it down:

- Maslow (Option 1)

- Maslow came up with the Need Hierarchy Theory. It basically says humans have different levels of needs, like food and safety first, then things like love, esteem, and self-fulfillment.

- Fayol (Option 2)

- Fayol is known for creating principles of management, like planning, organizing, and commanding, not a hierarchy of needs.

- Taylor (Option 3)

- Taylor is all about Scientific Management. He focused on improving work efficiency, not on personal needs or motivation theories like Maslow.

- Koontz (Option 4)

- Koontz wrote a lot about management theory but didn’t invent the need hierarchy concept.

So yes, Maslow is the one who gave us the “Need Hierarchy Theory of Motivation.” That’s the answer.
