The D or B I think.

It is not A or B, you need a comma after the day. Any guesses?

anonymous · Answer

It was D, by the way. On C, you need a comma after Wednesday. There is nothing wrong with C.

I mean there is nothing wrong with D, sorry :)

anonymous · Answer

Well i think is D or B because  in B have a comand after August.
