Answer to Question 1

B
The portion of the vascular tunic that contains the pigment responsible for the color of the eye is the iris.

Answer to Question 2

A
The eye is the sensory receptor of the visual system that transduces light from the environment into electrical impulses, which the optic nerve then transmits to the brain to be interpreted as vision. The fibrous tunic is the outer coat of the eyeball composed posteriorly of the sclera and anteriorly of the transparent cornea.
