gestalt psychology
b.
psychoanalytic theory
c.

d.
behaviorism

The correct answer is psychoanalytic theory (B)

Explanation:

psychoanalytic theory is the theory of personality organization and the dynamics of personality development that guides psychoanalysis, a clinical method for treating psychopathology. First laid out by Sigmund Freud in the late 19th century, psychoanalytic theory has undergone many refinements since his work. Psychoanalytic theory came to full prominence in the last third of the twentieth century as part of the flow of critical discourse regarding psychological treatments after the 1960s, long after Freud's death in 1939,[1] and its validity is now widely disputed or rejected.
