mikemcgarry, would the following be correct in this case (had it been an option)?
The state of California contains 58 counties, of which some have a population less than 10,000.
I realize that the post is old and I might be bothering you

Thanks in advance!
Dear
mohit2491I'm happy to respond.
My friend, your version is awkward and not at all how a native speaker would phrase it. I guess it's grammatically correct, but that's beside the point. The version that would be 100% correct in every respect is:
The state of California contains 58 counties, some of which have a population less than 10,000.
Does this make sense?
Mike

Hi Can you please tell me why 'B' is wrong?
sarathgopinath Quoting again what Mike said,
The word "which" is a relative pronoun. It introduces a subordinate clause and acts as the subject of that clause. Thus, the word "which" always needs a 100% bonafide full verb following it. If there were an option with a full verb after "which", that would be correct ---- that's what many test-takers would expect, and the fact that this option is not available is part of what is tricky about this question. It would be perfectly correct to say -----
The state of California contains 58 counties, some of which have a population less than 10,000.
That's completely correct, but not an option here. You see, choice (B) has "which" + [participle}, which is never a legitimate structure. The structure in (C), with the ordinary pronoun "them" + [participle] ---- that is a legitimate structure: an absolute phrase, discuss in the link in that first post.
Please give Kudos if this helped you.
