Correct answer: A. Increased prolactin concentration
- A. Increased prolactin concentration
- B. Reduced thyroid hormone release

Dopamine blockade in the tuberoinfundibular pathway can increase prolactin, causing galactorrhoea, breast enlargement and menstrual changes. The other options do not explain this typical antipsychotic effect.
