Given below are two statements \(:\) one is labelled as Assertion \((A)\) and the other is labelled as Reason \((R).\) Assertion \((A) :\) \(I - Cl\) is more reactive than \(I _{2}\). Reason \((R):\) \(I - Cl\) bond is weaker than \(I-I\) bond. 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 \((A)\) is not correct but \((R)\) is correct.
4. D Both \((A)\) and \((R)\) are correct and \((R)\) is the correct explanation of \((A).\)
