This kind of situation actually can create some amusing images. The rule is that an introductory phrase must modify the subject of a sentence. That being the case, the following word after "Listening in the park . . ." has to be someone that can listen; the words "no," "then," and "and," which begin answers a, b, and c can't listen--they have no ears. We can be certain that Alisa has ears though. See below for practice with introductory phrases.
