286. Even today, a century after Pasteur developed the first vaccine, rabies almost always kills its victims unless inoculated in the earliest stages of the disease.

(A) its victims unless inoculated
(B) its victims unless they are inoculated
(C) its victims unless inoculation is done
(D) the victims unless there is an inoculation
(E) the victims unless inoculated

Solution:

Pronoun*
A and C can be eliminated as due to the absence of a pronoun, it is not clear that who is inoculated.
For correct meaning of the sentence, ‘its’ is needed to specify that the victims are rabies victims. Hence, D and E can be eliminated.
B is the best choice.
