Final answer:
The correct answer is option C) G. Stanley Hall.
Step-by-step explanation:
The theorist who proposed that adolescence is a turbulent time of "storm and stress" in 1904 is G. Stanley Hall. He was a pioneer in the study of adolescent development.
While the theory by Erik Erikson also deals with stages of development, his focus was on psychosocial stages that span a person's entire lifespan, emphasizing the social nature of our development rather than its sexual nature, which contrasts with Freud's theory on psychosexual development.
It's important to note that contemporary research suggests that most teens don't experience adolescence as tumultuously as Hall once suggested.
