Which analyte affected by light exposure is a vitamin A form?

Light exposure can break down compounds with conjugated systems, and vitamin A forms like retinol are particularly susceptible to photodegradation. Because of that, samples containing vitamin A are kept in darkness or in amber containers to prevent loss of activity and ensure accurate measurements. Among the options, the analyte that is a vitamin A form is Vitamin A itself. The other items correspond to a thyroid hormone, another vitamin not in the A family, and bilirubin, which is light-sensitive for different reasons but is not a vitamin A form.
