GMAT Sentence Correction (SC) | Re: Of the top-grossing films of the 1980s, only a few, having a

I think we need a ", " in C to make it at least worthy to check it again.
I will go for B.
I don't know when to use "having " here it sounded awkward , compelling me to leave option A.
Can someone please explain the usage of having ( even in verb tenses ) . Links are also appreciated . Thank you.
