(A)because they are composed of tissues such as tooth and bone (B)because they are composed of tissues like tooth and bone that are (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

the answer is (E)

I got headache in this question. Can someone help translate it into Chinese?

What is the meaning of "tissue"? Are "tooth and bone" tissues? What is meaning of "tissues not normally found in the organ in which the tumor appears"? What is difference between "tissue" and "organ"?

I totally got lost. Thank you very much for your help!!!

Teratomas是普通的癌症形式，在于T是由tooth和bone之类的tissue(组织)组成的，这些组织通常没有在肿瘤出现的器官中被发现。

tissue - 组织；比如人体的神经组织、表皮组织、肿瘤等等，在偶看来，只要是个身体器官(organ)或器官生出来的东西(比如：tumor)都可以被看作是tissue的一个部分。
