Final answer:
B) Melanin is the pigment that absorbs ultraviolet radiation before it can damage mitochondrial DNA.
Step-by-step explanation:
The pigment which absorbs ultraviolet radiation before it can damage mitochondrial DNA is B) Melanin.
Melanin is a complex polymer that is naturally produced by our skin to protect it from the sun's ultraviolet radiation.
It absorbs the UV rays and prevents them from reaching and damaging our mitochondrial DNA.
For example, when we get a tan after spending time in the sun, it is the melanin in our skin that is responsible for absorbing the UV radiation and darkening our skin pigmentation.
