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 :

1. A Both (A) and (R) are true and (R) is the correct explanation of \((\mathbf{A})\)
2. B Both \((\mathbf{A})\) and \((\mathbf{R})\) are true but \((\mathbf{R})\) is not the correct explanation of \((\mathbf{A})\)
3. C (A) is false but (R) is true
4. D (A) is true but (\(\mathbf{R}\)) is false
