A, B, prevented from 前面有逗号，明显是个伴随状语， 那么它的逻辑主语就应该是Sound。 而Sound本身是不能发出prevent from dissipating阻止消散这个动作的，杀掉。同理杀掉E，逗号ing也是个伴随。
C和D：独立主格省略了连词with. D选项倒装还原后应该是as a result of boundaries in the ocean....., 缺逻辑主语 prevent energy from being dissipated. 另外这里being冗余，没有上下文的意思需要用到进行时。
C：正确。倒装还原为 Boundaries prevent energy from dissipating
