Final answer:
The safest option for the hunters walking single file is for the first hunter to wear bright orange, as it significantly increases visibility and reduces the risk of accidental harm.
Step-by-step explanation:
The question at hand involves identifying which of three hunters walking single file would be safe, based on their attire. The best option for safety while hunting is for hunters to wear bright colors, such as bright orange, which is highly visible and helps to distinguish humans from the natural environment. This is particularly important to prevent being mistaken for game by other hunters.
Given the choices:
- The first hunter wearing bright orange would be the safest choice, as this would make them most visible to other hunters.
- The second hunter wearing camouflage would not be as safe, because they blend in with their surroundings, making it harder for other hunters to see them.
- The third hunter wearing dark colors would also be unsafe, as dark colors do not stand out in the natural environment, increasing the risk of being mistaken for game.
Therefore, the correct answer is a) The first hunter wearing bright orange, as wearing bright colors, and specifically bright orange, is a widely recommended safety practice in hunting to increase visibility and safety.
