Music professor: Because rap musicians can work alone in a recording studio, they need not accommodate supporting musicians' wishes. Further, learning to rap is not as formal a process as learning an instrument. Thus, rap is an extremely individualistic and nontraditional musical form. Music critic: But rap appeals to tradition by using bits of older songs. Besides, the themes and styles of rap have developed into a tradition. And successful rap musicians do not perform purely idiosyncratically but conform their work to the preferences of the public. The music critic's response to the music professor's argument
A: challenges the grounds on which the music professor generalizes from the particular context of rap music to the broader context of musical tradition and individuality

C: challenges its conclusion concerning rap music by offering certain additional observations that the music professor does not take into account in his argument
D: challenges it by offering evidence against one of the stated premises on which its conclusion concerning rap music is based
