Consider the following phrases:
i. dominated by such brutal forces
ii. there certainly may be times when one's own culture, society and tradition are so reified
iii. When debate and conversation are so dried up or simply made impossible that the social critic
iv. becomes the social exile
To form a complete sentence, the correct order of the phrases above is:

(ii) talks about a situation where one's own culture, society and tradition are made to seem unquestionably real. (iii) carries the sentence forward stating the consequences of such a situation. The idea of it affecting the social critique due to the lack of debate and conversation is introduced. (i) reemphasises that it is the result of brutal forces that such a situation has happened. (iv) states what exactly happens to social critiques in such a case.
Hence the correct order is (ii)(iii)(i)(iv)
Therefore the correct answer is C.
