Correct answer: C — Stop and seek urgent full blood count assessment

Carbimazole can cause agranulocytosis. Fever, sore throat or mouth ulcers require urgent FBC and medical review. In this scenario, the correct option is stop and seek urgent full blood count assessment. The other options are plausible but do not address the key clinical, legal or safety issue as directly. This aligns with UK pharmacy practice guidance cited in the reference field.
