Solution

The correct option is C
Ultraviolet radiations

Ultraviolet waves have wavelength slightly shorter than that of visible light. Ultraviolet radiation is present in sunlight, and also produced by electric arcs and specialized lights such as mercury-vapor lamps, tanning lamps, and black lights. Although lacking the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions and causes many substances to glow or fluoresce.
