The correct answer is (d) None of these. All of the structures mentioned in the options have blood vessels associated with them.
The iris is the colored part of the eye and contains blood vessels that supply nutrients and oxygen to the tissues.
The lens is a transparent structure located behind the iris and does not have direct blood vessels. However, it is surrounded by a network of blood vessels called the ciliary processes, which secrete fluids necessary for the lens's function.
The ciliary muscles are a ring of smooth muscles located around the lens of the eye. Like the iris, they receive a blood supply through blood vessels.
Therefore, all the options mentioned have blood vessels associated with them in some way.
