The correct Answer is:
A
Ultraviolet (UV) radiation is part of the electromagnetic (light) spectrum that reaches the Earth from the Sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. These wavelengths are classified as UV-A, UV-B, or UV-C. UV-A is the longest of the three at 320-400 nanometers and is more dangerous than rest of all.
