Question

A person suffering from colour blindness cannot recognise

• A. Red and Yellow colours
• B. Red and Green colours
• C. Blue and Green colours
• D. None of these

Hint:

Answer 1

The Correct Option is B

The most common form of colour blindness is red-green colour blindness, where a person cannot distinguish between red and green colours. This is due to the absence or malfunction of red or green cones in the retina.
- Other combinations like red-yellow or blue-green are less common or not typical forms of colour blindness.
