Until Berta and Ernst Scharrer established the concept of neurosecretion in 1928, scientists believed that either cells secreted hormones, which made them endocrine cells and thus part of the endocrine system, or conducted electrical impulses, in which case they were nerve cells and thus part of the nervous system.

A.either cells secreted hormones, which made them
B.either cells secreted hormones, making them
C.either cells secreted hormones and were
D.cells either secreted hormones, in which case they were
我觉得选D最关键的原因还是在于or引导的平行结构:
cells either secreted hormones, in which case they were..., or conducted electrical impulses, in which case they were...
those two parts match too perfectly to be fallacious~
另外,个人认为they之所以指代cells而非hormones主要还是语义,毕竟hormones不是cells,所以通过语义判断,they指代cells没问题~
至于在in which case从句中they是否优先指代主句主语,我觉得应该是这样的,manhattan SC 5th中有说道代词的5大原则,其中最后一个“case”中有提到,不过书上的例句是从属关系的两个分句,而这里是主句和定语从句,不过应该是适用的,不太确定哈...
