123. She was less successful after she had emigrated to New York compared to her native Germany, photographer Lotte Jacobi nevertheless earned a small group of discerning admirers, and her photographs were eventually exhibited in prestigious galleries across the United States.
(A)     She was less successful after she had emigrated to New York compared to
(B)     Being less successful after she had emigrated to New York as compared to
(C)     Less successful after she emigrated to New York than she had been in
(D)     Although she was less successful after emigrating to New York when compared to
(E)     She had been less successful after emigrating to New York than in
答案是c


我比较纠结是首句是不是少了一个动词。一开始我觉得b好，因为有个being,后来看到有童鞋说那样就变成了她和她故乡德国比。
那是不是c应该是 (Being) less successful after she emigrated to New York than she had been in 更好呢？

少了个being我实在是看得浑身不舒服，这样到底是什么结构啊
