I picked C, and this is my reasoning:
most important A of MM -> CSR.
CSR depends less on AQ than on HL and how shots go together.
since this is an inference/make a conclusion question, we need to ID an answer choice that is true 100%.
(A) The artistic quality of the individual photographic image is unimportant in movie photography.
no, it cannot be inferred from the argument. The argument says that CSR is less dependent on AQ than on smth. this does not imply that AQ is unimportant.
(B) Photographers known for the superb artistic quality of their photographs are seldom effective as moviemakers.
this might be true, but not always. moreover "seldom effective" looks way to extreme for the conclusion. so out.
(C) Having the ability to produce photographs of superb artistic quality does not in itself guarantee having the ability to be a good moviemaker.
looks good. so CSR is less dependent on AQ than on other things. thus, someone who is especially good at AQ might not be a successful movie maker.
(D) Movie photographers who are good at their jobs rarely give serious thought to the artistic quality of the photographs they take.
rarely give - again, way to extreme for the conclusion. moreover, it cannot be inferred from the argument.
(E) To convey a scene’s rhythm effectively, a moviemaker must highlight many different aspects of the action taking place.
"must" - not good. the argument does not say that.
C so far is the best.
