To determine which inference about the narrator's feelings toward Abuela is best supported by the text, consider the context of their relationship as depicted in "Abuela Invents the Zero."
The most supported inference regarding the narrator's feelings is likely:
D. She is ashamed to be seen with Abuela.
This is often a theme explored in stories involving generational and cultural differences, where the narrator may struggle with their identity and may feel embarrassment or shame about being associated with an elder who may not fit into the perceived norms of the narrator’s environment.
However, without more specific text references, all options might have elements that could be supported depending on the details provided in the text. If the text strongly depicts the narrator's internal conflict regarding Abuela's presence, option D would be the best choice.
