285597 Benzenecarbaldehyde is reacted with concentrated NaOH solution to give the products \(A\) and \(B\). The product \(A\) can be used as food preservative and the product \(B\) is an aromatic hydroxy compound where OH group is linked to \(s p^3\) hybridised carbon atom next to benzene ring. The products \(A\) and \(B\) are respectively,

1 sodium benzoate and phenol
2 sodium benzoate and phenyl methanol
3 sodium benzoate and cresol
4 sodium benzoate and picric acid.
