Solution

The correct option is A Ultraviolet radiation
Melanin is a natural pigment which is produced from the oxidation of amino acid tyrosine and followed by polymerization. In humans, melanin production is initiated on exposure to UV radiation. Due to this, the skin gets darken. Melanin can effectively absorb UV light and dissipate about 99.5% of it, thus giving protection against UV radiation.
So, the correct answer is 'Ultraviolet radiation'.
