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？

"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?

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

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
