Answer 7

Also, for option A, Vital force theory is an old theory which said that any organic material has a vital force which only nature can provide and thus organic compounds can not be synthesised synthetically inside laboratories. But urea was the first synthetically synthesised organic compound and thus the vital force theory was discarded.
