Option 1 -> Creates awkward flow: "perch on the ground...hunt for prey detect meals" lacks proper connection between hunting and detecting.
Option 2 -> Proper sequence: subject introduction → location/purpose → method → object of detection. Flows naturally.
Option 3 -> Grammatically incorrect: "perch detect meals" lacks necessary transitional elements.
Option 4 -> Illogical order: places detection before establishing perching location and hunting context.
Hence, Option 2: (C), (B), (D), (A) -> The complete sentence reads: "Snowy owls, native to the Arctic tundra, perch on the ground or short posts to hunt for prey and use their excellent eyesight and keen hearing to detect meals hidden beneath snow or vegetation." This maintains logical progression from subject → action → location/purpose → methodology → outcome. -> correct
