According to abraham maslow, people are motivated by: question 3 options: a. optimal arousal. b. drive reduction. c. a hierarchy of needs. and) instincts.

c. hierarchy of needs 

Maslow founded the "hierarchy of needs" wherein it shows how an individual behavior is influenced by needs. People get motivated with this model since it gives us the understanding of human nature. 

He emphasized that in order to understand the human behavior, we need to understand first the human nature.  

It is our very nature to fulfill the needs of our body. That includes food, clothing and shelter; the basic needs. Ones this need is fulfilled, we can proceed to the next level and so on. And in order for us to achieve the highest level, we need to fulfill the lower levels first. 

A, B and D are not part of Maslow's work.
