1. One of the X's that/who <plural>
2. One of the X's <singular>
3. Only one of the X's <singular>
4. Only one of the X's that/who <plural>
5. The only one of the X's that/who <singular>

In your question though it's not the case when "One of the X's that/who <plural>" is used. It's the case of typical modifier error mis-introduced by examiner in this question. The sentence says that - "the patchwork surrounds ... town ..." AND "the patchwork ... bustles with farm workers ..."

The correct way of presenting this sentence would be - "In good years, the patchwork of green fields, that surrounds the San Joaquin Valley town, bustles with farm workers, many of whom are in the area just for the season.

as you see the examiner made likelihood of "run-on" mistake in this sentence

In good years, the patchwork of green fields that surround the San Joaquin Valley town bustles with farm workers, many of them in the area just for the season.

This SC is about Subject-verb agreement + Pronuns/Modifiers

This one is hard! Is it the fields that surround San Joaquin, or a patchwork (of fields) that surrounds? Grammatically both are correct, but only one answer correctly handles the farmers.

Nice. Didn't look it that way. Thanks guru!

The issues:

1. The words set off by COMMAS are non-essential modifiers; therefore, the skeleton of the sentence is:

In good years many of whom in the area just for the season.

The above sentence does not have a finite verb. Now search for the options that did not insert a verb.
A. Does not have verb. Eliminate it.
B. Has a verb.-------keep it.
C. Has a verb-------keep it.
D. Does not have a verb. Eliminate it.
E. Has a verb..........Keep it.

Now, second phase:

the patchwork of green fields that surround...

here, eliminate the middle man. We get the following:

the patchwork that surround..........

Patchwork is singular, so surround should be "surrounds".
--> Eliminate C and D.

we are between B and E.

In the option E, "Many are......" is problematic. We need "many of whom". Eliminate E.
