Answer:
d. oral
Step-by-step explanation:
Oral stage: In psychology, the term oral stage is the first stage in the theory of psychosexual development which was given by Sigmund Freud, and starts from the birth of the child and lasts through one and a half years of age. At this stage, a child learns oral gratification and therefore all the needs of the child should be satisfied through the process of thumb-sucking for example, keeping toys in mouth.
Any child who gets fixated tends to be over-dependent on the other person and therefore he or she seeks oral gratification or stimulation by drinking, smoking, or eating.
In the question above, Charlotte may be fixated at the oral stage of psychosocial development.
