Depopulation is about reducing an entire population quickly in response to urgent circumstances, such as an infectious disease outbreak or a natural disaster. This population-level action aims to stop spread or protect welfare across many animals, not just relieve suffering in an individual or produce food.

Euthanasia, by contrast, is the humane killing of an individual animal to relieve suffering from illness or injury, usually on a case-by-case basis, and it does not imply mass culling. Slaughter is the process of killing animals for human consumption under routine, humane handling standards, not in response to an urgent welfare or disease situation.

So the statement that best captures the concept of depopulation is the rapid destruction of a population in response to urgent circumstances. The other descriptions mix in aspects of euthanasia or slaughter that don’t describe the population-focused, emergency intent of depopulation.
