Question

Which place name has no errors in punctuation?

A.
Denver, Col

B.
Denver CO.

C.
Denver, CO

D.
Denver, C.O.

I think C or D.

Answer 1

What do you think it is?

Answer 2

C or D

Answer 3

D is incorrect.

It is C because you first name the City, then state.
a comma must separate the two as well.

Also the state has to be abbreviated in all caps. It doesn't require a '.' after or before or even in-between.

Hope I helped. :)

Answer 4
