Answer:
a. theory of self-actualization
Step-by-step explanation:
The theory of self-actualization, proposed by Abraham Maslow, is based on the belief that human beings have a hierarchy of needs. Maslow's hierarchy of needs suggests that individuals have a set of basic physiological needs, safety needs, social needs, esteem needs, and self-actualization needs. According to this theory, individuals strive to fulfill these needs in a hierarchical manner, with the fulfillment of basic needs being a prerequisite for the pursuit of higher-level needs.
