Question

As compared to rods, the cones are ............... times less sensitive to light.

• A. 100
• B. 200
• C. 300
• D. 400

Answer 1

Answer: (C)

300

• Rodes and cones are the two photoreceptors which are present in the retina of the eye.
  
• The cones are 30-300 times less sensitive to light than rods, but even this allows color vision at any intensity of light greater than very dim twilight.
  
• So, in dark or low light they can not function properly.
  

So, the correct answer is option C.
