Correct answer: D — Repeat thyroid function tests and consider levothyroxine if persistent symptomatic disease

This is subclinical hypothyroidism, and treatment depends on persistence, symptoms, antibody status and TSH level. Carbimazole and radioiodine treat hyperthyroidism, not raised TSH. Repeating tests avoids treating transient abnormalities.
