Final answer:
You should only shoot at a deer when it reappears in an open area, ensuring a clear view for an ethical and accurate shot.
Step-by-step explanation:
A deer disappearing into a clump of bushes presents a scenario where ethical hunting practices are essential. The correct time to shoot at the deer is when: A) It reappears in an open area. Shooting based on movement or noise alone is not a safe or ethical practice, as it does not ensure a clear identification of the target and can lead to accidents or the harming of non-target species. Likewise, seeing just the antlers is not sufficient to ensure a clear and ethical shot. A responsible hunter must have a clear view of the animal to ensure an accurate and humane shot, which can only be done when the deer is visible in an open area.
