I think it is C.
It is clearly between A & C.
A - There is no deemphasis here. But, there is repudiation(refusal to recognize) of the type of aestheics. The part of the sentence "It is one of the permanent gains ...........that we are rid of this type of aesthetics"
You get rid of something when you refuse to acknowledge it or you donot like it at all.
Thus, C is the answer.
Paul or Olegc may wanna jump in here to clarify the answer.
Nineteenth century art critics judged art by the realism of its method of representation. It was assumed that the realistic method developled from the primitive beginnings to the perfection of formal realism. It is one of the permanent gains of the aesthetic revolution of the twentieth century that we are rid of this type of aesthetics.
It can be infer from the passage above that the aesthetic revolution of the twentieth century had which of the following effects?
A. It deemphasized the realistic representation as an evaluative consideration for judging works of art.
B. It permitted modern critics to appreciate the simplicity of primitive art.
C. It repudiated the realistic of representation found in the art of the past.
D. It reinforced the traditional way of looking at and judging great art.
