Answer: Option A
:
A
Look at these lines -
“Postmodernism belies all grand narratives like those of positivism and even Habermas’s theory of rationality that try to force people into the mold of a specific way of thinking and acting”.
“Positivism and even Habermas’ theory of rationality, which under the guise of universality attempted to force people into a certain way of thinking and acting, as history has so adequately demonstrated, do not shrink from a totalitarian approach.”
From the above two lines we can infer that (a) could be right.
“As is evident from the above quotation, postmodernism believes all great narratives on the levels of both epistemology and social philosophy”.
We find that answer option is (c) is wrong.
Option (b) is out of scope. It is not mentioned anywhere in the passage that post modernism gives equal weightage to incommensurability and homogeneity.
So (a) is the correct answer.
