In the carbylamine reaction of a primary amine with $CHCl X_{3}$ and ethanolic $KOH$ , the reactive electrophilic species generated from chloroform is

Atrichloromethyl cation
Btrichloromethyl free radical
Cchlorine atom
Ddichlorocarbene

Answer: D

Chloroform loses HCl with base to give dichlorocarbene (a carbene with a vacant orbital). The amine nitrogen attacks it, and two further eliminations of HCl give the isocyanide R-NC.
