Four statements are given below at A, B, C and D. There may be some errors in the given statement(s). The incorrect statement is your answer.

Ans. E.
In the given sentences, boiled down is the phrasal verb that should have been used which means summarizing something, to reduce or simplify
(something) to the most basic, essential, or fundamental element(s). In this context it means that the one who had more power succeeded. 'Boiled down' should be followed by 'to' and not 'for', hence option D is incorrect.
