Solution
The correct option is A Meibomian glands
The lacrimal gland above the eye serves to secrete tears which are the dilute salt solution and serves to cleanse and moisten the eye surface. Conjunctiva serves to cover the anterior of the eye while eyelids are the continuation of skin and serve to protect the eyeball from debris. Harderian glands are vestigial organs in human but serve the minor role in lubrication of eye of terrestrial animals. Meibomian glands are the tiny oil glands present in a single row perpendicular to lid margin and serve to secrete meibum that makes the lipid layer of preocular tear film. The film prevents friction between eyelids and cornea. Thus, the correct answer is option D.
