Given below are two statements: one is labelled as Assertion \((A)\) and the other is labelled as Reason \((R)\). Assertion \((A)\) : Haloalkanes react with \(\mathrm{KCN}\) to form alkyl cyanides as a main product while with \(\mathrm{AgCN}\) form isocyanide as the main product. Reason \((R)\) : \(\mathrm{KCN}\) and \(\mathrm{AgCN}\) both are highly ionic compounds. In the light of the above statement, choose the most appropriate answer from the options given below:

1. A \((A)\) is correct but \((R)\) is not correct
2. B Both \((A)\) and \((R)\) are correct but \((R)\) is not the correct explanation of \((\mathrm{A})\)
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 \((A)\)
