When hunting in a group, what is a safe practice?

When hunting in a group, establishing a zone-of-fire for each hunter is a safe practice because it helps ensure that each hunter has a specific area where they can shoot without endangering others in the group. This practice helps prevent accidental shootings and promotes clear communication among hunters.

Options A, B, and D are not safe practices when hunting in a group. Sticking close together increases the risk of shooting someone accidentally, spreading out can result in decreased visibility and communication, and following behind each other creates potential for shooting someone in front unintentionally. This is why option C, establishing a zone-of-fire for each hunter, is the best and safest practice in a group hunting scenario.
