Assertion : For preparation of phenol from diazonium salt, benzene diazonium hydrogen sulphate is better than benzene diazonium chloride. Reason : This is an S_(N)1 reaction so Cl^(Theta) may attack phenyl cation, producing some chlorobenzene.

How many of the following reagents can give benzene from benzene diazonium salt? H_2O, CH_3CH_2OH, H_3PO_4 , H_3PO_2 , HCHO , CH_3COOH, RCHO
