Sound can travel through water for enormous distances, prevented from dissipating its acoustic energy as a result of 
                boundaries in the ocean created by water layers of different 
                temperatures and densities. 
                

A.prevented from dissipating its acoustic energy as a result of 
                    

B.prevented from having its acoustic energy dissipated by 
                    

C.its acoustic energy prevented from dissipating by 
                    

D.its acoustic energy prevented from being dissipated as 
                    a result of

这是独立主格？

原意为Sound can travel through water for enormous distances,
prevented from dissipating its acoustic energy by
            boundaries in the ocean created by water layers of different temperatures and densities.
            

因A选的as a result of 改变句意应使用by才正确所以将原句改写成c选项才可…
            

E选的, Ving放句尾表结果亦或伴随前面主句动作,但本主句表示Sound can travel through water for enormous distances并不会有造成preventing……….的动作所以E删…….

所以后面its acoustic energy prevented from dissipating by做同位语结构
