premise: At a children's festival, exactly four songs are performed, each exactly once: "Night's All Right," "Question Man," "Rhino Rock," and "Sammy." The songs are performed consecutively, each on a different one of exactly four instruments: flute, guitar, harmonica, or keyboard. The songs are performed in accordance with the following: The first song performed is not performed on the flute. If "Sammy" is performed on the keyboard, then "Rhino Rock" is performed on the harmonica. If "Question Man" is performed on the keyboard, then "Night's All Right" is performed on the flute. The song performed on the keyboard immediately follows "Rhino Rock" and immediately precedes "Night's All Right." Which one of the following could be an accurate matching of the four songs performed at the festival with the instruments on which they are performed, listed in order from the first song performed to the last?
