Solution

The correct options are
A Bromination of acetanilide
B Coupling reaction of aryldiazonium salts
Benzene diazonium chloride reacts with phenol in which the phenol; molecule at its para-position is coupled with the diazonium salt to form $p -$ hydroxy azobenzene. This type of reaction is known as a coupling reaction. This is an example of an electrophilic substitution reaction. The reaction can be shown as:
