Helen Grey doesn't seem as a pleasant person at all. It can be concluded from the poem that she enjoys attention, provokes men, makes them fall in love with her and then toys with them and rejects them.
First part of the poem shows all the things Helen Grey does, her behavior and actions, so any line from the first part could be the correct answer (in this case, answer A).
Second part of the poem serves as a warning, suggesting consequences of such behavior, and as a reminder that her beuty will disappear as years go by. All other given answers fall into this category.
Using short sentences makes the author sound rude. using run-on sentences makes the author seem super talkative. I suggest use medium length sentences to set the tone.
