D. its acoustic energy prevented from being dissipated as

E preventing its acoustic energy from dissipating by Here the doubt is really between B and E. Why E? - "prevented" - past participle used as adjective only and it cannot modify the entire clause and so we need "preventing". 2) "disspiate by" - idioms. (Dissiapiating by).

A. prevented from dissipating its acoustic energy as a
result of – In this kind of statements one has to look at the construction of sentence. Sound can travel and it can be regular/continuous/in frequent process, hence using ‘prevented’ will not help as it indicates that the process is finished as it is not the case.
B. prevented from having its acoustic energy dissipated by - In this kind of statements one has to look at the construction of sentence. Sound can travel and it can be regular/continuous/in frequent process, hence using ‘prevented’ will not help as it indicates that the process is finished as it is not the case.
C. its acoustic energy prevented from dissipating by – usage of its is for water or sound? And again prevented is not required.
D. its acoustic energy prevented from being dissipated as
a result of- usage of its is for water or sound? And again prevented is not required.
E preventing its acoustic energy from dissipating by – preventing indicates present continuous process.
I hope I made myself clear in replying.

what's the source of this question? I picked E because it's the only answer that contains the "ing" form... however, it's very strange for me that the right answer has some "by" Thanks

A,B and E are worng as they mean that the sound is preventing its coustic energy from dissipating, however it is the boundries that are preventing as in C and D. D is rejected for using "being". So IMO C.

Friends..Sorry for the wrong IMO..it is having a reference issue in C and D.. A has distorted meaning..B again has reference issue of "it"..So best pick is E...

this explanation surprised me....
This question is from Official Verbal Review (2nd Edition)-SC Q108 to be specific.
Here's the official explain
A Dissipating is not a transitive verb, so acoustic energy cannot function as its object.
B This version of the sentence is wordy, awkward, and indirect; from having... by erroneously suggests that the boundaries in the ocean are attempting to dissipate sound energy.
C Correct. Here, acoustic energy is effectively modified by the participial prevented from dissipating....
D This version of the sentence is wordy, awkward, and indirect; being dissipated as a result of makes it unclear whether the boundaries contribute to energy loss or prevent it.
E This version of the sentence nonsensically explains that sound prevents the dissipation of its own energy.

checked on other forums and OA is C.
"dissipating by" is the correct idiom.
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 - changes the meaning. "Sound" is not prevented. "acoustic energy" is prevented from dissipating
B. prevented from having its acoustic energy dissipated by - same as A
C. its acoustic energy prevented from dissipating by - CORRECT
D. its acoustic energy prevented from being dissipated as a result of - wordy and 'being' is incorrect.
E. preventing its acoustic energy from dissipating by - same as A. This sounds like sound is preventing its accoustic energy.

E. preventing its acoustic energy from dissipating by - same as A. This sounds like sound is preventing its accoustic energy. C is the best. Nicely explained Seekmba. There is another way of eliminating A,B & E are acoustic energy [as a result of, dissipated by, from dissipating by] they alter the meaning and creates confusion whether the energy is being prevented or produced/dissipated from boundaries.. out of C & D. C is concise and coherent.

The OA is C
The source is Verbal Review 2nd Ed
I'm confused about the structure of the sentence. According to the explanation from the book, "prevented..." is a participial phrase modifying the noun "acoustic energy". Since there is no conjunction between "distances" and "its", is the second part of the sentence an appositive (noun phrase)? If the second part is an appositive, which noun is it modifying?
Main clause
"Sound can travel through water for enormous distances,
its acoustic energy prevented from dissipating by boundaries in the ocean created by water layers of different temperatures and densities."

+1 C Cannot be E because it seems that the sound is dissipating.

C is better because E changes the meaning even though E is a choice which can easily be jumped on!
