Exposure to which of the following radiations can cause skin problems?

AInfrared
BUltraviolet ✓ Correct
CGamma rays
DNone of the above
Correct answer: (B) Ultraviolet
Explanation

Exposure to ultraviolet radiation can cause skin problems such as sunburn and skin cancer.

Infrared is mainly felt as heat and is not the chief cause of skin disease here.

Gamma rays are dangerous but come from radioactive sources, not the everyday skin risk asked.

Because ultraviolet is the clear cause, none-of-these does not apply.

Ultraviolet penetrates the skin and damages the DNA in its cells.

Sunscreen and protective clothing block much of this harmful radiation.
