Solution
The correct option is B UV rays
Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, which is shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight constituting about 10% of the total light output of the Sun. Sunlight is composed of about 1500 wavelengths, but the only wavelength that makes your body produce vitamin D are UV-rays when they hit exposed skin. Also, UV rays produce Vitamin D in the plants.
