Explanation:

The mammalian eye has several parts that work together to bend (refract) light rays, which is crucial for focusing images onto the retina.

- Cornea: The cornea is the clear, outer layer of the eye that strongly refracts (bends) incoming light rays as they enter the eye. It is the primary refractive surface of the eye.

- Lens: The lens is a flexible, transparent structure located behind the cornea. It further bends light rays to fine-tune the focus, adjusting to changes in the distance of the viewed object (a process called accommodation).

Together, the cornea and lens provide the majority of the eye's focusing power.


Let’s look at the other options:

#B. cornea and aqueous humour
- While the cornea refracts light, the aqueous humour does not significantly bend light. It helps maintain the shape of the eye and provides nutrients but is not involved in refracting light.

#C. cornea and vitreous humour
- The cornea does bend light, but the vitreous humour (the gel-like substance filling the eye) does not significantly bend light. It helps maintain the shape of the eye and supports the retina.

#D. lens and aqueous humour
- The lens does bend light, but the aqueous humour is not involved in bending light.

#E. lens and vitreous humour
- The lens bends light, but the vitreous humour does not play a major role in refracting light.


Summary:
The cornea and lens are the parts of the mammalian eye that strongly bend light rays to help focus images on the retina.
