GWD-8-2 究竟正确答案是D还是E

Q2:
Thelonious Monk, who was a jazz pianist and composer, produced a body of work both
rooted in the stride-piano tradition of Willie (The Lion) Smith and Duke Ellington, yet in
many ways he stood apart from the mainstream jazz repertory.
A. Thelonious Monk, who was a jazz pianist and composer, produced a body of
work both rooted
B. Thelonious Monk, the jazz pianist and composer, produced a body of work that
was rooted both
C. Jazz pianist and composer Thelonious Monk, who produced a body of work
rooted
D. Jazz pianist and composer Thelonious Monk produced a body of work that was
rooted
E. Jazz pianist and composer Thelonious Monk produced a body of work rooted both

我手边的两套答案上面正确答案都是D，可是我觉得D的that was多余，并且原句中的both...and...结构也没有保留。

还是觉得应该选E.

请NN指点

我是这样想的

both...and...并列的短语不一致，both对应的是介词短语，而and之后跟的是名词

不知道对不对，第一次发贴，嘿嘿，请高手指点

这里的both and是根本是个wordy，加了反而不知所云，而that be的省略不是一个绝对错误，og从来没有说过that be不省略就一定是错的

谢谢！现在明白了

Jazz pianist and composer Thelonious Monk

这里有没有歧义，Jazz pianist是一个人，composer TM又是一个人
