I am able to D and E because of missing that.
C is incorrect because of which, its creating a doubt in logic.
I was confused between A and B. So i went with the shorter sentence and Hence selected A. I couldnt find any reason to select the best answer.
Can you please help me in understanding the modifier concept here and how its applied?
Cheers,

With pleasure

When ever you see such hugely worded questions, you can remove
prepositional phrases, (modifiers in the non-underlined portion) etc, to easily identify the SV pair.
A study
of food resources in the North Pacific between 1989 and 1996 revealed
that creatures of the seabed were suffering from dwindling food supplies, possibly resulting from increasing sea surface temperatures during the same period.
A) that creatures of the seabed were
suffering from dwindling food supplies, possibly resulting from increasing
creatures of the bed were suffering because of some reason. They don't suffer from dwindling food supplies. (you suffer from/with something abstract. You don't suffer from a proper noun)
B) that creatures of the seabed were suffering because
food supplies were dwindling, possibly as a result of an increase in
Why were the creatures suffering? because of dwindling food supplies. How did this happen? As a result of an increase in ..
Perfectly fine.
C) that creatures of the seabed were suffering
because of food supplies, which were dwindling possibly as a result of increasing
This sentence means that creatures were suffering because of food supplies. The sentence actually means that the creatures were suffering because food supplies are dwindling.
D)
creatures of the seabed
that were suffering from
food supplies that were dwindling, possibly
resulting from an increase in
Lot of issues here. Creatures were suffering from food supplies? Absolutely wrong. The
modifier is modifying the preceding clause (wrongly)
E)
creatures of the seabed that were suffering because food supplies
were dwindling, which possibly
resulted from increasing
Creatures were dwindling? This isn't the intended meaning.
