Answer:
b) Ricky's need for belongingness is not being met.
Explanation:
Maslow developed a theory based on the needs of the human beings, he proposed a hierarchy of needs that is usually represented as a pyramid.
According to Maslow, needs lower down in the hierarchy need to be satisfied in order to focus in needs that are higher up in the pyramid.
The needs he proposed are:
Ricky is a highly ranked partner in a law firm (esteem needs), he has a lavish house with an elaborate security system and a luxurious car (physiological needs and safety needs), however, he is discontent with life.
Ricky lives by himself and does not find the time to socialize, thus, we can say that his love and belongingness needs are not being fulfilled since he has no interpersonal relationships.
Thus, according to Maslow's theory, this discontentment could be explain by the fact that b) Ricky's need for belongingness is not being met.
