B. conjunctiva `to` cornea `to` lens (through pupil) `to` aqueous humour `to` viteous humour `to` retina
C. conjunctiva `to` cornea `to` vitreous humour `to` lens (through pupil) `to` aqueous humour `to` retina
D. conjunctiva `to` cornea `to` aqueous humour `to` lens (through pupil) `to` vitreous humour `to` retina

Explanation

**Step-by-Step Solution:**

1. **Conjunctiva**: The first part that light rays encounter when entering the eye is the conjunctiva. This thin membrane provides protection and lubrication to the eye.

2. **Cornea**: After passing through the conjunctiva, light rays then enter the cornea. The cornea is responsible for bending (refracting) the light rays to help focus them.

3. **Aqueous Humor**: Next, the light travels through the aqueous humor, which is the clear fluid in the anterior chamber of the eye. This fluid nourishes the eye and maintains intraocular pressure.

4. **Lens**: The light then reaches the lens, which further focuses the light rays. The lens can change shape to allow us to see clearly at various distances.

5. **Vitreous Humor**: After passing through the lens, the light moves into the vitreous humor, a gel-like substance that fills the space between the lens and the retina. It helps maintain the shape of the eye and transmits light to the retina.

6. **Retina**: Finally, the light rays reach the retina, where they are converted into neural signals. The retina contains photoreceptor cells that detect light and send signals to the brain for visual processing.

**Final Pathway**: The correct path taken by light rays in the eyeball is: Conjunctiva → Cornea → Aqueous Humor → Lens → Vitreous Humor → Retina.

**Answer**: The correct answer is option B.
