According to psychologist Abraham Maslow, a person must have their physical needs, the need to feel safe, the need to belong, and the need for esteem in order to reach self-actualization.

To determine the correct answer, we need to understand the concept of self-actualization and how Maslow categorizes human needs.

Self-actualization is the highest level in Maslow's hierarchy of needs, which is a theory that explains human motivation. Maslow proposed that individuals have a hierarchy of needs that must be met in a specific order. Once the basic physiological needs, safety needs, social needs, and esteem needs are fulfilled, individuals can strive for self-actualization.

Option B is the correct answer: self-actualization.
