Answer:
A. She gets distracted when Raymond climbs the fence.
Explanation:
The story describes the moment Squeaky wins in the following way:
"And by the time he comes over I’m jumping up and down so glad to see him—my brother Raymond, a great runner in the family tradition. But of course everyone thinks I’m jumping up and down because the men on the loudspeaker have finally gotten themselves together and compared notes and are announcing, “In first place—Miss Hazel Elizabeth Deborah Parker.”"
Squeaky seems to get distracted when she sees that Raymond is climbing the fence. She is extremely happy to see him, and her attention is focused on this event. This means that she is unable to hear when the winners are announced and she does not immediately realize she won.
