The correct option is A Ceruminous gland
Ceruminous glands are specialized sudoriferous glands (sweat glands) located subcutaneously in the external auditory canal. Ceruminous glands are simple, coiled, tubular glands made up of an inner secretory layer of cells and an outer myoepithelial layer of cells. The glands drain into larger ducts, which then drain into the guard hairs that reside in the external auditory canal.
