Andrew ended up moving to Los Angeles to pursue a career in acting. After six months, Andrew became a busboy in an exclusive restaurant in Los Angeles where he serves very wealthy and even famous patrons. He starts to compare his life circumstances to those of the customers and begins forming negative self-feelings and hostility. Andrew's reaction is a response to

a. unmet expectations
b. collective efficacy.
c. deprived gratification.
d. relative deprivation.

d) Relative deprivation.

Explanation:

Relative deprivation is defined as the process in which a person tends to compares himself/herself with other person or group of individuals that should also persist. Resources like lifestyle, food, wealth, career etc is relatively expected by person to have rather than others as it is admired in the society.

According to the question, Andrew's response of getting frustrated after comparing his life status with other customer's life as he also wanted the amenities and resources in his life is due to relative deprivation. He think he has poor and worse circumstance than other.

Other options are incorrect because collective efficacy, expectations that have not been met and deprived gratification is not the way of comparison done by a person with other and perceive own situation as worst. Thus, the correct option is option(d).
