In Freud's terms, blockage of normal sexual development at some stage is called

A) repression.
B) fixation.
C) sublimation.
D) catharsis.

According to Freud's psychosexual theory, fixation is the blockage of normal sexual development at a particular stage. This can occur if the child does not successfully navigate the challenges and conflicts of that stage, leading to a fixation on that stage and potentially causing issues in adulthood. Repression is the unconscious blocking of unpleasant thoughts or memories, sublimation is redirecting sexual or aggressive impulses into socially acceptable behavior, and catharsis is the release of emotional tension through expression or discharge.
