Explanation:

The hadalpelagic zone is mainly found in ocean trenches. Trenches are a key characteristic of this zone. The underworld (B) is too vague. Bioluminescent (C) is a feature of some organisms in other zones too. Floor (D) is too general as many ocean areas have a floor. So trench (A) is the best nickname to remember the hadalpelagic zone's distinguishing characteristic.

A. trench
