Which of the following is a method for dispatching furbearers?

The use of carbon monoxide as a method for dispatching furbearers is grounded in its effectiveness and efficiency. Carbon monoxide is a colorless, odorless gas that, when inhaled, binds to hemoglobin in the blood more effectively than oxygen does. This leads to suffocation at the cellular level, making it a humane option for dispatching wildlife, as it causes unconsciousness and death relatively quickly if administered correctly.

Tranquilizers, while they can immobilize an animal, do not necessarily result in a swift or humane death, as the animal may remain conscious for an extended period, potentially experiencing distress. Baiting refers to attracting wildlife using bait, but it does not relate directly to the act of dispatching the animals. Tethering involves restraining an animal and is not a method for dispatching it. Therefore, the selection of carbon monoxide stands out as a recognized method for effectively and compassionately dealing with furbearers.
