Just completed e-GMAT course yesterday on same topic so confident about answer B. I go with it.

Definitely B is good..

(B)

There can be multiple potential grammatical antecedents for a pronoun, but if only one is logical then the usage is correct. But C still has the other issues that I mentioned above.

Thank you for the explanation, Jen. Could you please throw some light on answer choice as to why there is no parallelism, because, I couldn't find an error in it.

A. as much relief on the victor's side than it did on the vanquished.-- As mush as
B. as much relief among the victors as among the vanquished. -- my choice
C. as much relief on the victor's side as it did on the vanquished's. - Avoid apostrophes
D. relief both on the victor's side as well as on the vanquished's. - Emphasis is lost
E. relief both for the victor and the vanquished side.

- Emphasis is lost

OA is B

As... than and both... as well as are not right so delete A, D.

my answer is C.

I go with C, it's more clear than B,

My answer is C, because all the others seem to be grammatically incorrect, especially the one's apostrophe s

A. as much relief on the victor's side than it did on the vanquished.
B. as much relief among the victors as among the vanquished.
C. as much relief on the victor's side as it did on the vanquished's.
D. relief both on the victor's side as well as on the vanquished's.
E. relief both for the victor and the vanquished side.

The usage is "as...as", hence, I eliminated A, D, and E upon reviewing the choices. Between B and C, I considered 2 things, a) does the possessive make sense in C and b) which of the two is the most concise approach. As had been previously mentioned, it makes much more sense for a person to feel relief than for a side to feel relief; and even if C were grammatically correct, B would still be the more concise choice of the two.

B IS THE ANSWER

B IS THE ANSWER

Really a good question. I think in Option C ,, the use of "did" is wrong as there is no verb in the first part.

After arduous months of fighting, the sight of the white flag being raised generated as much relief on the victor's side than it did on the vanquished.

(A) as much relief on the victor's side than it did on the vanquished.
(B) as much relief among the victors as among the vanquished.
(C) as much relief on the victor's side as it did on the vanquished's.
(D) relief both on the victor's side as well as on the vanquished's.
(E) relief both for the victor and the vanquished side.
IMO: B
As much as
