Correct answer: D — Occupational urticaria with possible animal-protein asthma

Immediate wheals after contact suggest occupational contact urticaria, and wheeze during cage-cleaning raises concern about respiratory sensitisation. Animal proteins are recognised occupational sensitisers. Management should include exposure control, skin and respiratory assessment, and prompt referral if asthma is suspected.
