高手请帮我解答下这道英语题

Louis T. Wright, a surgeon, developed ingenious orthopedic braces, ___, and supervised the first use of Aureomycin on human patients.
　(A) treating skull fractures that he pioneered in 　　　 (B) pioneered in treating skull fractures
　　(C) which pioneered in treating skull fractures 　　　 (D) he was a pioneer in the treatment of skull fractures
为什么答案不是C

Answer 1

developed ingenious orthopedic braces

pioneered in treating skull fractures

and supervised the first use of Aureomycin on human patients.

三个是并列的，都是Louis T. Wright, a surgeon所做的事。
选C的话，which pioneered in treating skull fractures是形容braces的，后面就不能再接and supervised the first use of Aureomycin on human patients这句话了

Answer 2

你看下句子就知道这里是并列三个谓语动词
developed pioneered supervised

只有B合适

Answer 3

注意and, 空格处缺少和developed、supervised并列的谓语动词，因此选择（B）。

路易斯T.赖特，是一名外科医生，制定了巧妙的的矫形牙套，___，监督第一次使用金霉素的人类患者

(C)which 没有对象吧0反正C不顺眼．．0

Answer 4

是Louis T. Wright pioneered in treating skull fractures，用who连接

这里developed...，pioneered...，and supervised ...三个动词并列。
