Solution

The correct option is B UV rays
Non-ionizing radiation is a low energy electromagnetic waves which are insufficient to cause ionization. It includes electric and magnetic fields, radio waves, microwaves, infrared, ultraviolet, and visible radiation. UV rays are highly injurious to living organisms, since DNA and proteins of living organisms preferentially absorb UV rays, and its high energy breaks the chemical bonds within these molecules. It causes aging of the skin, damage to skin cells and various types of skin cancers. In the human eye, cornea absorbs UV-B radiation, and a high dose of UV-B causes inflammation of the cornea, called as snow-blindness, cataract, etc. Such exposure may permanently damage the cornea.
