The authors in various stories develop characters through other characters dialogue in ways of describing how a character feels towards the main character which express is how the author feels about the character.
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.
Hey mate!
You stuck?
I remember this story! :)
The answer is B. Asking the white children in his neighborhood to help him learn to read. In chapter VII, the quote, "Douglass's plan to learn to read centered on making friends with the poor white children of Baltimore and learning from them a little at a time," gives evidence of this fact.
Hope this helps! :)
