Sentence Correction

After many years of feeling separated by a great divide, the doctor now finds himself besides the lawyer, working with one another against HMOs and big tobacco.

A besides the lawyer, working with one another
B besides the lawyer, working with each other
C beside the lawyer, working with each other
D beside the lawyer, working with him
E beside the lawyer, working with one another

IMO C

A and B are out because of "besides"
working is modifying the entire clause, and in the clause two person were mentioned.
So, "each other" fits well here.

imo --C

me three C....LOL

IMO C as well

E is close but incorrect due to the following reason

Use each other when referring to two people. Use one another when referring to more than two people:
Example: The two friends embraced each other.
Example: The basketball team high-fived one another.

Thanks guys.
I chose C too.
OA is D
OE : Choice (C) can also be eliminated because it changes the correct one another (used when there are two nouns, as here) to each other (used with more than two nouns). However, there is another problem in the sentence. The subject of the sentence is the doctor . The doctor finds himself beside the lawyer and also working with the lawyer . It doesn't make sense to say that the doctor is... working with one another as the original sentence and Choice (E) say. Choice (D) working with him (the lawyer) is the only construction that makes sense.

Pops,

Each other: means for inclusive i.e doctor and lawyer together.
Another: some third party only those 2.

IMO C

I read the concept in many places.

"Each other" for only 2 parties
"One another" for more than 2 parties involved

Nancy and Adam share every thing with each other.
The students in the class share the books with one another.

working with... modifies the doctor, so it makes sense to say 'working with him, since the doctor is working with the lawyer

I am confused here-
X finds himself now beside Y ,working with each other for Z
Does ",working" not modify the entire clause "X finds himself now beside Y"

why working with pointing to X?

In this sentence, each other, would make the sentence nonsensical. It would imply that the doctor is working with HIMSELF and the lawyer to fight the HMOs.
