3) A can be eliminated because the passage does not talk about all plausible explanations and then choose one. It's only hypothesizing and we don't know if any of it is correct. (C), (D) and (E)- all introduce elements, not in the passage and hence is out of scope.

That is additional information.

The line is basically this

Indeed, some fisheries base the detection of their prey on the bioluminescence that the fish excite.


It is a valuable tool for fisheries interested in increasing their catch of fish that prey on plankton.
