Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Electromagnetic waves carry energy but not momentum. Reason (\(\mathbf{R}\)): Mass of a photon is zero. In the light of the above statements, choose the most appropriate answer from the options given below :

• A

  Both (A) and (R) are true and (R) is the correct explanation of \((\mathbf{A})\)
• B

  Both \((\mathbf{A})\) and \((\mathbf{R})\) are true but \((\mathbf{R})\) is not the correct explanation of \((\mathbf{A})\)
• Correct answer
  C

  (A) is false but (R) is true
• D

  (A) is true but (\(\mathbf{R}\)) is false

Hence, the correct answer is option: 'C'.
