The correct option is A.
Step-by-step explanation:
The perspective that focuses on the idea that we are full of sexual and aggressive conflicts is Psychoanalysis. This was a groundbreaking theory established by Sigmund Freud, who posited that our personality is shaped by unconscious forces. According to Freud, the personality structure comprises three parts: the id, ego, and superego. The id operates on the pleasure principle, seeking instant gratification for our sexual and aggressive urges. The ego, which functions on the reality principle, mediates between the id and the superego. Lastly, the superego represents the internalized societal rules and strives for perfection.
Freud also believed that psychosexual stages in early childhood play a critical role in personality development. He suggested that individuals may become fixated at a stage if it is unresolved, potentially leading to various personality issues. Freud's insights laid the foundation for future theories and practices in psychology, including the work of neo-Freudians who adapted his theories.
