Answer:
A. Abraham Maslow
Explanation:
Maslow made the hierarchy of needs literally called Maslow's Hierarchy of Needs. The hierarchy is in the form of a pyramid; a person works their way up the pyramid, starting at the bottom, to the most important need at the top. In order from bottom to top the needs are Physiological needs, Safety, Love, Self-esteem, and Self-actualization. Each stage becomes harder to master the higher up on the pyramid it is.
