Answer :
(c) Carbuncles are a collection of infected hair follicles that often occur on the back of the neck, the upper back, and lateral thighs that form a mass that evolves into an erythematous, painful, edematous mass, which drains through many openings.
Hair follicles are a small tube like opening or pore that inhabit the roots of the hair strand. The top two layers of the skin together form the hair follicle. Around 20 types of cells together form the hair follicle.
Erythematous refers to the redness of the skin or the mucous membrane due to the accumulation of blood in the dilated capillaries of that region. The condition can arise either due to some injury or due to infection.
