Using who vs that as first split
B & D are out

C has comparison problem-we need are for we are comparing actions.
between A & E

Assertive managers and compromising managers display a nice parallelism in E.

so sticking with E

ninad8 · Answer

The sentence is trying to convey that even though it is surprising, it is more likely for assertive managers to use collaborative methods more effectively than managers who use compromise. The last part of the sentence ("share and search for solutions that result in satisfaction among conflicting parties") is a modifier for the managers who are compromising.

In each of the options A to D, the subject of the first clause of the sentence is "assertive managers". Hence, the second dependent clause after the comma is modifying "assertive managers". However, it should be modifying the "compromising managers" which is taken care of by option E.

Surprisingly, assertive managers are more likely to use collaborative methods  more effectively than are managers who use compromise, sharing and searching for solutions  that result in satisfaction among conflicting parties.

(A) more effectively than are  managers who use compromise , sharing and searching for solutions
 'sharing and searching for solutions' modifies compromise..awkward meaning and illogical..hence, incorrect

(B) more effectively than are managers  that  use compromise, sharing and searching for solutions
 'that' is an incorrect relative pronoun; 'who' should be used..hence, incorrect

(C) to greater effect than  managers who use compromise , sharing and searching for solutions
 incorrect parallelism..'assertive managers' is not parallel to 'managers who use compromise'

(D) to greater effect than are  managers that use compromise , both sharing and searching for solutions
 'that' is an incorrect relative pronoun; 'who' should be used..Also, there is incorrect parallelism..'assertive managers' is not parallel to 'managers who use compromise'
 
(E) more effectively than are  compromising managers   who  both share and search for solutions
 Correct parallelism..'assertive managers' is parallel to 'compromising managers'...Also, 'who' is an correct relative pronoun to be used..hence. CORRECT option

(E) is the CORRECT option

I looked up the Collins Dictionary, the only meaning of the word  compromising  is wrong / embarrassing. 
Therefore, it is not likely that "a compromising manager" means a manager that is willing to compromise. 
Given this, I don't think that E is the correct answer.
Can anyone explain?
