Solution
The correct option is D UV rays
The intermediary lobe of the pituitary gland secreted the Melanocyte Stimulating Hormone (MSH) that acts on the types of cells in the skin called the melanocytes. These cells produce a coloured pigment called the melanin which diverts the UV-A radiations falling on the skin. This prevents the UV rays from reaching to the other sensitive cells of the body and prevents the possible damages to the DNA that can be caused by them. This is the reason that body develops tanning when exposed to the bright sunlight. It is a protective mechanism.Hence, the correct answer is 'UV rays'.
