Yes, the answer is certainly A. You can confirm this from an
OG 10 question given below whose OA is A. Therefore, I don’t think we need to entertain any doubts the authenticity of the double negative ‘not unlike’, since it has been already accepted by
OG.
Quote:
While Jackie Robinson was a Brooklyn Dodger, his courage in the face of physical threats and verbal attacks was not unlike that of Rosa Parks, who refused to move to the back of a bus in Montgomery, Alabama.
(A) not unlike that of Rosa Parks, who refused
(B) not unlike Rosa Parks, who refused
(C) like Rosa Parks and her refusal
(D) like that of Rosa Parks for refusing
(E) as that of Rosa Parks, who refused
The problem with using ‘as’ for comparing nouns is that, it is often taken to be comparing X in the role of Y. For example, X is very good as a captain, meaning that X is very good in the role of the captain or X is very good as a finisher, meaning that he is very good in the final few slog overs. One might notice that the true essence of comparison is lost when ‘as’ is used for comparison between nouns. That is why E is not to be preferred over A.
The second point to note about this topic is that per se, the pronoun ‘its’ stands for the battalion’s. Its bravery is being compared with the bravery of Russian counterparts. It is not clear to which country does the battalion belong to. It could be Britain or France or for that matter any other country. You might see, the original
OG does not mention ‘its’ and avoids the unnecessary doubts. . This is just an observation.
