which指 hormones，them 指cell 的话，不符合逻辑

从meaning看应该是整个句子made them endocrine cells，而which不能指代句子

which指代hormones，而这里的意思是cells分泌了hormones，这种情况它们是endocrine cells，而不是说hormones使它们变成了endocrine cells。

通过平行能判断应该是D，从句意上讲，是说在科学家认为细胞分泌荷尔蒙，in which case，指代这一种情况（即上述的一句话), 而单单用which的话，则只能指代hormones

看到后面的 in which case they were，用平行
