The correct answer is:
Key Idea : $1^{\circ}$ amines form diazonium salts at low temperature and diazonium salts are weak electrophiles, so react with strongly activated ring. (takes $\mathrm{H}$ from benzene nucleus).
Note : The $-\mathrm{N}=\mathrm{N}-$ linkage is called -azo linkage, and the reactions in which azo or diazo compounds are formed, are called diazo coupling reactions.
