The correct answer is D. An over gratification of needs at that stage
Step-by-step explanation:
Regression, as proposed by the psychoanalyst Sigmund Freud, occurs as one individual goes back to a previous stage instead of coping with a current stage. For example, one of the stages proposed is the oral stage (birth to 18 months old) this stage involves the individual obtaining pleasure through the mouth by sucking, eating, biting, etc. and can lead to individuals eating excessively or smoking in later stages due to regression. Additionally, according to Freud regression occurs due to inhibition, stress or over gratification or indulgence which means there was an excess of stimuli in the stage. Thus, regression may be related to "an over gratification of needs at that stage".
