Under Muslim Law, divorce by common consent is known as:- (A) Talaq-e-Tafwid (B) Khula (C) Lian (D)…

Divorce by consent under Muslim law is effected through Khula (at the wife's instance, on returning consideration) and Mubarat (by mutual agreement), so the correct combination is "(B) and (D) only". Talaq-e-tafwid is delegated divorce and Lian is by mutual imprecation, so they are excluded.
