$(I)$ and $(II)$

Vedclass · Answer

(C) The middle layer of the eye is the choroid,which becomes thick on the anterior side to form the ciliary body. The ciliary body continues forward to form the iris. In front of the lens,the aperture surrounded by the iris is called the pupil. Statement $(I)$ is correct as the pupil is the aperture surrounded by the iris. Statement $(II)$ is correct because the iris contains smooth muscle fibres (sphincter pupillae and dilator pupillae) that regulate the diameter of the pupil. Statement $(III)$ is incorrect because the transparent crystalline structure attached to the ciliary body is the lens,not the pupil. Therefore,statements $(I)$ and $(II)$ are correct.
