Answer:
The correct answer is:
A. referent
Explanation:
Referent power was first described by the two social psychologists John French and Bertram Raven in 1959. They explained how the influence of an individual, normally with high leadership skills, has a great impact on people's behavior. Referent power is reflected as a kind of personal power in which collaboration and influence become more important than the idea to rule or control the environment.
