SC: Griffith's cameraman Blitzer

Griffith's cameraman Blitzer was a mechanical wizard, and what skill was lacking in his visual composition was more than compensated by his ability to combine gadgets and props to produce the required cinematic effects.
(A) what skill was lacking in his visual composition was more than compensated by
(B) what skills he was lacking in visual composition, he more than compensated for in
(C) whatever his visual composition lacked, he more than compensated in
(D) whatever skills he lacked in visual composition, he more than compensated for by
(E) he more than compensated his lack of visual composition with

Solution:-

A) --> "Compensated By" -> Incorrect Idiom
B) --> "Compensated for" -> Correct Idiom. So it is CORRECT CHOICE
C) --> Altered Meaning. He lacked the skill of visual composition, not his visual composition lacked any skills.
D) --> Sounds good but "for by" is pinching to me.
E) --> [Though I am not still sure about the reason of omitting this option] trying to compare two different things. "Lack of visual composition" is not something that we can compare with his ability. I guess, it should be treated as "flaw" rather than "skills".
