Assertion : A famous painting was painted by not using brush strokes in the usual manner, but rather a myriad of small colour dots. In this painting the colour you see at any given place on the painting changes as you move away. Reason : The angular separation of adjacent dots changes with the distance from the painting.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion

Step-by-step solution

For the human eye, the resolving power or angular separation of objects changes as distance from the object changes. Thus when we are close to the painting our eyes can pick out the separate colours of dots. But when we move away from the painting, our eyes blend the dots and we see different colours.
