Upon a deep psychological analysis of 'Deficiency Needs' (D-Needs) and 'Growth Needs' (B-Needs) in Abraham Maslow's Hierarchy of Needs Theory, which of the following options most accurately explains the philosophical and motivational difference between these two categories that determines the direction of human motivation?

According to Abraham Maslow's theory of hierarchy of needs, lower-level needs such as physiological, safety, love, and esteem needs are called 'Deficiency Needs' (D-Needs) because their absence creates a deficit in the body or mind, and motivation temporarily ceases when they are fulfilled. Conversely, 'Self-Actualization' at the top of the hierarchy is a 'Growth Need' (B-Needs), which motivates a person not to fulfill a deficiency, but to continually advance their inner potentials, creativity, and mental development.
