GWD3-Q29:

Unlike the conviction held by many of her colleagues that genes were relatively simple and static, Barbara McClintock adhered to her own more complicated ideas about how genes might operate, and in 1983, at the age of 81, was awarded a Nobel Prize for her discovery that the genes in corn are capable of moving from one chromosomal site to another.

A.      Unlike the conviction held by many of her colleagues that genes were relatively simple and static

B.       Although many of her colleagues were of the conviction of genes being relatively simple and static

C.      Contrary to many of her colleagues being convinced that genes were relatively simple and static

D.      Even though many of her colleagues were convinced that genes were relatively simple and static

E.       Even with many of her colleagues convinced of genes being relatively simple and static

看到网上的一篇帖子说根据being可以省略可排除B和E

但总感觉不太明白，being在这里到底有什么错误呢？

being的用法是什么呢？

希望各位牛牛指点下~
