DDT is prepared by heating chlorobenzene with

Acarbon tetrachloride and $AlCl X_{3}$
Bphosgene and $Zn$
Cchloroform and aqueous $NaOH$
Dchloral, $CCl X_{3} CHO$ , in the presence of conc. $H X_{2} SO X_{4}$

Answer: D

Two molecules of chlorobenzene condense with one molecule of chloral,

CCl X_{3} CHO

, with conc.
