The quotation from About Russell that best supports the inference that the author is worried about her brother's welfare is the third one: "Rusell didn't talk, let alone look at me. The chess set was still standing there, pieces and all".

Explanation:

In these lines, the author expresses her concern when she describes her brother's attitude, when she says "Rusell didn't talk, let alone look at me" she is describing a person who isn't even capable of looking in the eye to another one, isn't capable of talking with someone close to him and this is a very serious issue, it demonstrates that he is not well.
