Question

Match column I with column II and select the correct option from the codes given below.

Column I	Column II
A. Cornea	(i) Provides opening for light to enter
B. Iris	(ii) Transduces blue, green and red light
C. Lens	(iii) Controls the amount of light that enters
D. Optic nerves	(iv) Alters the shape of lens
E. Pupil	(v) Transmit information to the CNS
F. Ciliary muscles	(vi) Focus light directly on retina
G. Fovea	(vii) Bends light and protects inner eye

• A. A - (vii), B - (iii), C - (vi), D - (v), E - (i), F - (iv), G - (ii)
• B. A - (i), B - (ii), C - (iii), D - (iv), E - (v), F - (vi), G - (vii)
• C. A - (vii), B - (vi), C - (v), D - i(v), E - (iii), F - (ii), G - (i)
• D. A - (vii), B - (iv), C - (vi), D - (v), E - (i), F - (iii), G - (ii)

Answer 1

The correct option is A A - (vii), B - (iii), C - (vi), D - (v), E - (i), F - (iv), G - (ii)

A. A-(vii), B-(iii), C-(vi), D-(v), E-(i), F-(iv), G-(ii)

Reason:

• Cornea bends the light and protects inner eye from the environment.
  
• Iris controls the amount of light that enters into the eye.
  
• Lens focuses light directly on retina and forms a proper image.
  
• Optic nerve transmits information to the CNS for analysing.
  
• Pupil provides opening for light to enter into the inner eye.
  
• Ciliary muscles alters the shape of lens to adjust the focus.
  

Fovea transduces blue, green and red light.

So the correct option is A.
