A. is a run-on sentence. It connects two independent clauses with a comma. It should be replaced by either a semicolon or a period.
Oh, I see. Thanks!
You're welcome.

Please don't change screen names -- at least for the same subject.
Oh, sorry about that.
Wait a second. But is "Take public transportation" an independent clause?
i don't think it is.
Yes. "Take public transportation" is an independent clause. Because it's an imperative sentence, the subject (You) is understood.
