Many of them refers to the farmworkers, so it should be whom and has to be followed with are.

So, IMO B

but "surrounds " is not agree with the plural subject, I mean "green fields" !!
I would prefer C with "whom" instead of "who"
any taker ?!

IMO A
Surrounds is used to show present tense
patchwork of green fields......surround
(A) surround the San Joaquin Valley town bustles with farm workers, many of them ---> Correct
(B) surrounds the San Joaquin Valley town bustles with farm workers, many of whom are ---> Surrounds incorrect, Bcoz referred to patchwork, Whom is incorrect too
(C) surround the San Joaquin Valley town bustles with farm workers, many of who are ---> Who usage is incorrect
(D) surround the San Joaquin Valley town bustle with farm workers, many of which --> Which is for things
(E) surrounds the San Joaquin Valley town bustles with farm workers, many are ---> Surrounds incorrect, Bcoz referred to patchwork

I think the subject is "patchwork" not green fields.

B is best as explained above.

IMO A
Surrounds is used to show present tense
patchwork of green fields......surround
(A) surround the San Joaquin Valley town bustles with farm workers, many of them ---> Correct

But, isn't "bustles" also signify present tense in A?

@scorpion.ks
check this out , I got it from Psahil's note :
A sentence like ‘X is one of the Y that are. Are is the correct use. Such a sentence always should have a subject verb agreement with Y and not with X.

obviously we need "are" in the second part , so rule out A and D .
B and E have S-V flaw ! so left with C ! although I still have problem with "who" !!

[sourav106]

Surrounds is used to show present tense
this was flaw in my reasoning i feel....

[faust]

IMO B is the correct answer, patchwork is the subject of the sentence, hence surround needs to agree with patchwork. Soltan - of is the middleman, it's there to confuse you. Farm workers is not the subject of the sentence, whom needs to be use instead of who. You only use who to refer the subject.

[soltan]

in second thought may be you are right ! since it doesn't have "one " !!! I am lost dude !!
