Answer: C. self-actualization.
Abraham Maslow formulated the Hierarchy of Needs. This theory describes the hierarchical structure of human needs. Some needs are considered basic to all humans while others aren’t. These needs are placed in a pyramid and at the bottom of the pyramid, is food, which is considered a basic need for human survival.
At the peak of the hierarchy is self-actualization. Self-actualization according to Maslow simply refers to an individual achieving his/her goals or full potential. Maslow, together with other humanistic theorists, self-actualization is a by-product of the positive aspects of human nature. Self-actualization is achieved by only a small percentage of people.
