What is the primary reason to tell someone your return plan before hunting?

Informing someone of your return plan before heading out to hunt is primarily about safety in case of emergencies. Sharing your plan helps ensure that someone is aware of your location and estimated return time. If anything goes wrong, such as an accident or getting lost, that person can provide critical information to authorities or search parties, enhancing the chances of a timely rescue.

The other options may hold some validity in different contexts but do not prioritize the fundamental aspect of safety as effectively. Promoting teamwork, while valuable, does not focus specifically on safety concerns that are crucial when you're in potentially hazardous outdoor environments. Avoiding attention from game and keeping track of hunting locations are more about the hunting strategy itself rather than the safety measures that are essential when hunting away from others.
