Verified by Experts

The correct Answer is:
B
Alkali fusion of the sulphonate salt :
`PhHoverset(H_(2)S_(2)O_(7))rarrPhSO_(3)H underset(2.H^(+))overset(1.NaOH ,330^(@)C)rarrPhOH`
Benzene is suphonated with oleum `(H_(2)SO_(4)//SO_(3))` and benzene sulphonic acid is converted to sodium phenoxide on heating with molten sodium hydroxide.Acidification of the sodium salt gives phenol
