Answer:
C. "He never asked us for anything, nor did he go about begging other people for money."
This text from 'About Russell' best supports the inference that the narrator eventually learns to accept her brother for who he is.
Russell was now a grown up man and was unemployable by the standards of most organisations. The narrator was initially embarrassed when she came to know that her brother was collecting soda bottles from other people's garbage and redeeming them for a nickel a piece. Then her sister Rosalind explained to her that their brother kept his pride intact and never asked them for any help or begged from their acquaintances for money. He did whatever he could to manage his life on his own and always kept quiet about his problems and sufferings.
