Solution

The correct option is A Oxidation
The absorption of UV light, mainly from sunlight, degrades polymers in two ways. UV light degrades polymers and it can make polymers brittle. Oxidation is a degradation phenomenon when the electrons in a polymeric bond are so strongly attracted to oxygen atoms outside the bond that the polymer bond breaks.
