Quizplus · Accepted Answer

According to Freudian theory, the oral stage of psychosexual development occurs from birth to 18 months, during which the primary focus of pleasure is on the mouth. If the child does not successfully transition from this stage and move on to the next stage, a fixation can occur. This fixation can manifest in later life as behaviors such as thumb-sucking or nail-biting. Therefore, the best answer is B, a fixation at the oral stage of psychosexual development.
