Solution

B. It is you who are responsible for the downfall.

Explanation

Option A is incorrect as here the word "politics" is singular as it is denoting a subject of study. Thus, the verb should be "is" instead of "are". Option B is grammatically correct. Option C is incorrect as the order of pronoun is incorrect in the sentence. When some pleasant news is to be announced, the speaker uses this order: II person, III person and I person, and when some unpleasant news is to be announced, he uses this order: I person, II person and III person. For example : You, she and I have been commended for the success of the project. I, you and she have been held responsible for the failure of the project. Option D is incorrect because with the names of river, we use definite article "the". So, it should be "The Ganga" in the sentence.
