Please provide explanation.
A and B - "humanize" sound. It is prevented from dissipating .........ain't happening
C - concise, well worded. Keep
D - being is wordy and awkward
E - the water is preventing the dissipation. This happens because an 'ing' usually tries to summarize the result of the preceding clause. Which in this case is non-sensical.

Hence C

OA please?

Please provide explanation.
In my understanding:

Sound cannot prevent (water prevents, sound is prevented) its acoustic energy from being dissipated.

So passive voice is needed here. Only A and B remain.

For the second bold phrase : The sound does not dissipate its acoustic energy, something does (maybe "boundaries in the ocean created by water layers of different temperatures and densities" does.)
B has the passive voice phrase: "having its acoustic energy dissipated by"

Hence, I'll go with B.
OA pls.

The OA is C.

The earlier BTG thread (linked above by uwhusky) has some excellent discussions, peppered with Stacey's and Ron's useful posts.
