Always underline the part of statement in SC question.

A is my answer

B,D,E are discounted because they compare 'among friendly competitors' with 'bitter competitors'.
These sentences should have 'among' before bitter

C is discounted because if we remove the modifiers, the sentence looks like this
Tacit collusion leads to undesirable consequences which harms consumers...
when the harming part is actually caused by oligopoly

Is the answer correct?

IMO, D (but C looks OK as well)

More common among friendly competitors than among bitter rivals,the undesirable consequences of tacit collusion often include oligopoly ,which harms consumers by raising prices above efficient levels

A. Miscplaced modifier
B. Lack of parallelism in introduction: leading to... and more common
C. This one looks OK to me as well. I don't like the ending 'often including' which sounds akward
E. Misplaced modifier

@barron: we don not need to repeat 'among' I think because it is implied (is is what Kaplan 800 calls an ellipsis)

What is OA?

among should be used before both comparable things..

C is very awkword and its the disturbances which is common not the conclusion
