I believe your answer would have to be A. " he"
Direct characterization is when the author specifically tells the reader the traits of a character. In this excerpt, Dickens tells you that the woman is elderly, wise, experienced and knows what is "good for children". If Dickens had used indirect characterization, he would have need to shown her wisdom and experience by including specific examples. The reader would then be lead to develop his own conclusion about the whether or not the woman was wise and experienced.
A would be the answer on my behalf
Me. I would have to come before the subject, (Patti) and mine would be focused on the prize instead of the person, in this case, you and Patti
