Q: Which vitamin is produced in the human body by the action of sunlight on the skin?

The correct answer is D. Vitamin D is synthesized in the skin when 7-dehydrocholesterol is converted to cholecalciferol by UVB radiation from sunlight. This is why Vitamin D is called the 'sunshine vitamin'. Memory trick: D for 'Daylight' - Vitamin D comes from sunlight exposure.
