Abraham Maslow suggested that those who fulfill their potential have satisfied the need for

A) implicit memories.
B) an ideal self.
C) self-actualization.
D) unconditional positive regard.

Maslow's hierarchy of needs suggests that people have a basic set of physiological and safety needs which must be met before they can move on to higher level of needs such as social and esteem needs. Ultimately, the highest level of need is self-actualization, which involves fulfilling one's potential and achieving personal growth and fulfillment. Therefore, the answer is C - self-actualization, as this is the need that must be met in order to reach one's full potential.
