Australia has one of the highest skin cancer incidence and mortality rates in the world. It is caused mainly due to the exposure to UV rays. Which of the following UV rays are responsible for this?

Correct option is C

The correct answer is (c) Both UV-A & UV-B.
· UV-A and UV-B rays are both responsible for causing skin damage that can lead to skin cancer. Prolonged exposure to these ultraviolet rays, especially from the sun, increases the risk of skin cancer. UV-B rays cause direct damage to the DNA in skin cells, while UV-A rays penetrate deeper into the skin and contribute to skin aging and indirect DNA damage.
Information Booster:
· UV-A: These rays penetrate deeply into the skin and contribute to skin aging and long-term skin damage. While they are less intense than UV-B, they are more prevalent and can also contribute to skin cancer.
· UV-B: These rays are more intense and responsible for sunburns and direct DNA damage in skin cells, which can lead to skin cancer.
· UV rays not responsible: This option is incorrect, as UV rays, particularly UV-A and UV-B, are well-documented causes of skin cancer.
