Given below are two statements: One is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A\) : \(Image-I\) can be easily reduced using \(Zn - Hg / HCl\) to \(Image-II\) Reason \(R : Zn - Hg / HCl\) is used to reduce carbonyl group to \(- CH _2-\) group. In the light of the above statements, choose the correct answer from the options given below:

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