To prove: that subsidy actually worked.
(A) takes for granted that the subsidy’s intended purpose could have been achieved if the subsidy had not existed (how would the rural people be able to access electricity at all, if no subsidy is provided? The subsidy system might have not worked in most rural area, but what about other rural type areas?) (Incorrect)
(B) takes for granted that if a subsidy has any benefit for those whom it was not intended to benefit, then that subsidy has failed to achieve its intended purpose(the subsidy is meant to benefit rural people, no other type of household is provided with subsidy) (Out of Context)
(C) presumes, without providing justification, that the intended purpose of the subsidy was to benefit not only rural populations in the nation who have no electricity, but other people in the nation as well(No, only rural households were meant to get subsidy not other people) (Incorrect)
(D) overlooks the possibility that even many of the people in the nation who live in urban areas would have difficulty gaining access to electricity without the subsidy (it's already given that urban households have access to electricity. The subsidy is meant to provide electricity in rural areas at economical rates) (Incorrect)
(E) fails to take into account that the subsidy could have helped many of the rural residents in the nation gain access to electricity even if many other rural residents in the nation were not helped in this way. (As stated, even if the most rural households are unable to get electricity, the subsidy system did worked by providing electricity to many other rural residents) (Correct)
