The question that you would not ask yourself while making a feeling-attitude inference is:
D. Why is she so happy?
Feeling-attitude inference involves making an interpretation of the emotional state or attitude of a person based on their verbal and nonverbal cues. It involves identifying and analyzing the emotional and attitudinal aspects of the message, rather than the reasons behind them. Therefore, asking why the person is happy goes beyond the scope of feeling-attitude inference and delves into the underlying reasons for the emotional state. The other options A, B, and C are all relevant questions to ask while making a feeling-attitude inference.
