Given below are two statements: one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A :\) The escape velocities of planet \(A\) and \(B\) are same. But \(A\) and \(B\) are of unequal mass. Reason \(R :\) The product of their mass and radius must be same, \(M _{1} R _{1}= M _{2} R _{2}\) In the light of the above statements, choose the most appropriate answer from the options given below

1. A Both \(A\) and \(R\) are correct but \(R\) is \(NOT\) the correct explanation of \(A\)
2. B \(A\) is correct but \(R\) is not correct
3. C Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\)
4. D \(A\) is not correct but \(R\) is correct
