我觉得肯恩故事你对状语从句的使用不是特别清晰。

像E，主句是：many spare teeth lie in seemingly limitless reserve，这里有一个地点状语从句in the shark’s jaws修饰lie，逻辑主语是lie的主语many spare teeth 。从句是：each one ready to slide into the appropriate position whenever an active tooth is lost or worn down 这里整整一句是做独立主格结构做状语修饰主句的动词lie，表伴随的动作。然后在这个从句的层次里面，又有一个状语从句whenever an active tooth is lost or worn down 修饰each one ready to slide into the appropriate position 。

但是原句重心应该是：When an active tooth in the shark’s jaws is lost or worn down作为状语从句修饰many spare teeth lie in seemingly limitless reserve。

修饰语位置的不同，很显然，句子的意思就很大的不同了。

另外，D错误是因为The many spare teeth垂悬，整个句子没有谓语动词。

C错误是除了each od them 和谓语 are 主谓不一致外，也犯了E的毛病。

B错误是因为which从句指代the shark’s jaws，逻辑意思不对。

希望这样的解释是正确的。
