Which animals must be stopped and reported if killed or injured?

The correct choice identifies specific domesticated livestock and pets that have significant value, and that may also pose safety risks if involved in a collision or injury situation. In emergency response scenarios, it is crucial to report incidents involving these animals, as they can belong to individuals or agricultural operations and may lead to legal or financial implications.

Additionally, domesticated animals like dogs, horses, and livestock such as cattle and sheep can pose a threat to public safety if they are on roadways or if their injuries result in changes in traffic flow. The responsibility to react appropriately in such situations includes notifying authorities for the safe handling of these animals. This aligns with both ethical considerations and community safety standards, as well as the regulatory expectations in emergency response protocols.

Other options include animals that typically do not have the same level of social and economic impact or that may be considered wild or nuisance animals, meaning they do not require the same level of reporting in most emergency response procedures.
