Maslow,an early humanist,believed in four areas of the most basic needs that must be in place for a person to self-actualize.The four areas are:

A) physiological, mental, love/belonging, esteem.
B) physiological, mental, love/belonging, emotional.
C) physiological, safety, love/belonging, emotional.
D) physiological, safety, love/belonging, esteem.

According to Maslow's hierarchy of needs, the most basic needs that must be met for a person to self-actualize are physiological needs such as food, water, and shelter, followed by safety needs such as security and stability. The third level is love/belonging needs, which include social connections and intimacy. Finally, esteem needs such as recognition and achieving a sense of accomplishment must be met before a person can reach self-actualization. Therefore, option D is the correct choice as it includes all four of these basic needs.
