company limited

Which one is the correct short form of "company limited"?
a) Co. Ltd.
b) Co., Ltd.
if b) is the correct one, then why there is a comma after Co. because I don't see other abbreviation has a comma after it.

In my experience, "Co., Ltd." is the most common. The comma has nothing to do with the abbreviation. It is there or not there based on the original words. This is actually "The Thomas Company, Limited" with "limited" being a legal designation.

So do you mean "Co. Ltd." is also correct. i.e., "The Thomas Company Limited" is correct without a comma?

In my opinion, it should have a comma. Nevertheless, with the considerable variation in punctuation styles, I wouldn't be surprised if there are those who disagree.
