Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Knowing initial position \( x_{0} \) and initial momentum \( p_{0} \) is enough to determine the position and momentum at any time \( t \) for a simple harmonic motion with a given angular frequency \( \omega \).
Reason (R) : The amplitude and phase can be expressed in terms of \( x_{0} \) and \( p_{0} \).
In the light of the above statements, choose the correct answer from the option given below:
