Correct answer: D — Work-related asthma or irritant asthma from disinfectant exposure

Cleaning agents can cause or aggravate asthma through sensitising or irritant mechanisms. The task-specific pattern and improvement with lower-aerosol methods support a work-related diagnosis. Exposure control, substitution and respiratory assessment are appropriate.
