During a psychiatric assessment, a client displays behaviors consistent with fixation at the oral stage of Freud's psychosexual development. Which of the following behaviors would most likely indicate oral fixation according to Freud's theory?

Rationale: A. According to Freud, oral fixation stems from issues during the oral stage (birth to 18 months), and it may manifest in behaviors involving the mouth, such as smoking, overeating, drinking, or nail-biting. B. While dependency may be related, it's more generalized and not the most specific indicator of oral fixation. C. These are characteristic of anal fixation, associated with the anal stage (1–3 years), often due to strict toilet training. D. Rebelliousness and authority issues are more aligned with adolescent psychosocial development (e.g., Erikson’s identity vs. role confusion), not Freud’s oral stage.
