Question

Which sentence does not contain any punctuation errors?

Answer 1

I would say D.  I know it looks weird, but that doesn't have anything to do with it. There needs to be a period after Friday because it is abbreviated, and there also needs to be a comma after Friday because a month comes next. There also needs to be a period after October because it is abbreviated. And then there is a period after 12 because it's  the end of the sentence.
