246．Joachim Raff and Giacomo Meyerbeer are examples of the kind of composer who receives popular acclaim while living, often goes into decline after death, and never regains popularity again.

(A)  often goes into decline after death, and never regains popularity again

(B)   whose reputation declines after death and never regains its status again

(C)  but whose reputation declines after death and never regains its former status

(D)  who declines in reputation after death and who never regained popularity again

(E)   then has declined in reputation after death and never regained popularity

请高手指点下：（不考虑其它选C的原因）but 用来并列从句前面不应该用逗号，而此处but前有逗号，这是怎么回事啊？

谢谢sissi, but 用来并列从句前面没逗号，并列主句有逗号，依你的回答，这里即考平行，又连接从句啊，为什么有逗号啊？
