Whenever she considers voting in an election to select one candidate for a position and there is at least one issue important to her, Kay uses the following principle in choosing which course of action to take: it is acceptable for me to vote for a candidate whose opinions differ from mine on at least one issue important to me whenever I disagree with each of the other candidates on even more such issues; it is otherwise unacceptable to vote for that candidate. In the upcoming mayoral election, the three candidates are Legrand, Medina, and Norton. There is only one issue important to Kay, and only Medina shares her opinion on that issue.

Summary
When there’s at least one issue important to Kay, then it’s acceptable for her to vote for a person with whom she disagrees on an important issue IF she disagrees with every other candidate on a greater number of important issues. If she does not disagree with every other candidate on a greater number of important issues, she cannot vote for a person with whom she disagrees about an important issue. In the upcoming election, the three candidates are L, M, and N. There’s only 1 issue important to Kay. Kay agrees with M on that issue, but she disagrees with N and L on that issue.

Notable Valid Inferences
The question stem asks us to draw an inference about "any" election. So we should pick an answer that logically follows from one of the principles. The details about the upcoming mayoral election aren't relevant to this question stem.

A
If there are no issues important to her, it is unacceptable for her to vote for any candidate in the election.
Could be false. We don’t know what is acceptable or unacceptable when there are no issues important to Kay.
B
If she agrees with each of the candidates on most of the issues important to her, it is unacceptable for her to vote for any candidate in the election.
Could be false. It’s acceptable for her to vote for one of the candidates if she disagrees with all the other candidates on a greater number of important issues. Maybe she agrees with one cand. on 80% of imp. issues, but with the other candidates only on 70%.
C
If she agrees with a particular candidate on only one issue important to her, it is unacceptable for her to vote for that candidate.
Could be false. It’s acceptable for her to vote for that candidate if she disagrees with each of the other candidates on a greater number of important issues. She might disagree with the other candidates on every issue, for example.
D
If she disagrees with each of the candidates on exactly three issues important to her, it is unacceptable for her to vote for any candidate in the election.
Must be true. If she doesn’t disagree with each of the other candidates on a greater number of important issues, it’s unacceptable for her to vote for a candidate with whom she disagrees on an important issue. Here, she disagrees with each candidate on the same # of imp. issues.
E
If there are more issues important to her on which she disagrees with a particular candidate than there are such issues on which she agrees with that candidate, it is unacceptable for her to vote for that candidate.
Could be false. It’s acceptable for her to vote for that candidate if she disagrees with each other candidate on a greater number of important issues. She might disagree with one candidate on 55% of imp. issues, but disagree with everyone else on 70%, for example.
