A- Complex. When a sentence contains the word "when," it is complex. Hope this helps.
B, works of arts or books, use quotes in the name. Also being how A+D are the same, and C uses half which doesn't happen normally, certain rules.<span />
Taking notes about a speaker's topic before hearing the speech
I guess the paragraph break should be after the B) Ellen asked and "How are you feeling?" and Ellen said. Because while reading this dialog, reader need a pause between the information which these characters exchange. In my opinion, there must be graphical and emotional space between their introduction and next action that hasn't revealed yet. Also, I'd choose B to make this conversation looks alive.
