{D} "being" is not needed here... also, "as a result of" is generally used for the meaning "because of some phenomenon"
Also, i don't agree with OA.. can you please cross-check

Hi tandon_puneet,
This SC requires proper use of Modification rules. Answer E is incorrect because it implies that "Sound" is preventing its acoustic energy from dissipating. The non-underlined back-half of the sentence shows us that it's "...boundaries in the ocean..." that are preventing the acoustic energy from dissipating.
GMAT assassins aren't born, they're made,

Generally, COMMA + VERBed serves to modify the preceding noun.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
E preventing its acoustic energy from dissipating by
A and B: ...enormous distances, prevented from dissipating...
Here, prevented seems to modify distances, implying that the DISTANCES are prevented from dissipating.
Not the intended meaning.
Eliminate A and B.
Generally, the agent of a COMMA + VERBing modifier must be the SUBJECT of the preceding clause.
E: Sound can travel through water for enormous distances, preventing its acoustic energy from dissipating.
Here, preventing seems to refer to sound (the preceding subject), implying that SOUND is PREVENTING its own energy from dissipating.
Not the intended meaning.
Eliminate E.
In D, as a result of boundaries implies that the boundaries themselves are RESULTING in something.
Not the intended meaning.
The boundaries themselves cannot result in something; only an ACTION or an EVENT can result in something.
Eliminate D.
The correct answer is C.
OA: 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.
Here, the portion is red is an ABSOLUTE PHRASE.
