Given below are two statements: one is labelled as Assertion

\mathbf{A}

and the other is labelled as Reason R. Assertion A: Number of photons increases with increase in frequency of light. Reason R: Maximum kinetic energy of emitted electrons increases with the frequency of incident radiation. In the light of the above statements, choose the most appropriate answer from the options given below:

A
$\mathbf{A}$ is not correct but $\mathbf{R}$ is correct.
B
$\mathbf{A}$ is correct but $\mathbf{R}$ is not correct.
C
Both $\mathbf{A}$ and $\mathbf{R}$ are correct and $\mathbf{R}$ is the correct explanation of $\mathbf{A}$ .
D
Both $\mathbf{A}$ and $\mathbf{R}$ are correct and $\mathbf{R}$ is NOT the correct explanation of $\mathbf{A}$ .
