Answer:
When looking at the collectivist need hierarchy, when someone does service to the society, they are:
A. self-actualized.
Step-by-step explanation:
The concepts referred to in the question were introduced by American psychologist Abraham Maslow (1908-1970).
According to Maslow's theory, there is a hierarchy of needs that goes from the most basic ones to the higher, more psychological and abstract ones. For instance, our most basic needs are physiological (food, water, air, reproductions, etc.) As the lower needs are satisfied, we begin to seek to fulfill higher needs.
On the top of the pyramid, we find the need for self-actualization, which Maslow described as the need to be everything one can be. Self-actualized people look beyond themselves and seek to help others. They often adopt a cause, advocating and fighting for it. They are generous with their time and often seek to do social services or donations.
With that in mind, we can choose letter A as the best option.
