I had been asked this question by my school principal while I was bunking the class.

Question is from Amines Nomenclature in section Amines of Chemistry – Class 12

Answer 1

The correct option is (d) N,N-Diphenylaniline

To elaborate: It is a secondary aromatic amine that will be formed. One of the phenyl groups will be considered as a substituent on nitrogen atom (N-phenyl) and the other will act as aniline with the N atom.
