(C) because they are composed of tissues, like tooth and bone, tissues
(D) in that their composition, tissues such as tooth and bone, is
(E) in that they are composed of tissues such as tooth and bone, tissues

Why the answer is (E) ,没有人觉得E这句话理顺的话如下：Teratomas are unusual forms of cancer in that they are composed of tissues such as tooth and bone, tissues not normally found in the organ in which the tumor appears.

斜体句子是一个独立的句子吧？！那前面也没有连词不就是错误句型吗？RUN ON 句型？那为啥还要选e

B/C, 举例用such as 而非Like，排除

D, in that their composition, tissue such as tooth and bone, is .....  从句中subject 不清晰，且“their composition" awkward

A, generates ambiguity.  "not normally found" referring to ”tissue“ or to”tooth and bone" .  根据句意来看，应该是“在别的器官中不常见的组织”

所以E是最清晰的

斜体的句子不是一个独立的句子  它是tooth and bone的同位语从句

"such as" and "like" are not interchangeable, answers B and C are eliminated. In D subject-verb agreement rule is violated, as for A it seems only "bone" is midified by the following clause. E must be correct I think.
in addition, a needs an "," . right?

为什么好多人都说D违背了主谓一致原则？composition不就是应该接is么？
