Explanation:

Correct Answer is (a).The given statement implies that the people of Telengana will have opinions about him with respect to his past actions and not what he will do in the future. It seems that the sentence is about support to a political party on the basis of its actions in the last few years.
Option B is not correct because it does not make the statement meaningful. The first blank may be filled with reject which will imply that the people of Telengana will reject him anyway but the second blank will not be filled with restricts since that will make the whole sentence illogical.
Option C is not correct because the first word given for the first blank does not fit in the context and there is no point thinking over the second word given. This can be eliminated safely as reciprocate implies doing the same thing to somebody in return and it is about supporting some party and not doing the same to it, in the given context.
Option D is also not correct because the people cannot rectify him as that is illogical in terms of the usage of the word in this context. There is no point considering the second word given for the second blank.
Option A is correct because people of the state are going to judge the political party and its leader on the basis of its actions in the last few years in power and he may now say something that he wants to do in the next few years but that is of no use now as far as getting support of people is concerned.
It makes option A the correct choice among the given options.
