Assertion : The increase in wavelength due to doppler effect is termed as red shift.
Reason : In red shift, a wavelength in the middle of the visible region of the spectrum moves towards the violet end of the spectrum.

A

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

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.
