Which action should be taken to signal for help during a survival situation?

Using emergency flares is the most effective way to signal for help during a survival situation. Flares are designed for long-distance visibility and can be seen from great distances, especially at night or in low-light conditions. They provide a clear and unmistakable signal to rescuers that someone is in distress and needs assistance.

While yelling continuously may seem like a viable option, it can be less effective than visual signals, particularly in noisy environments or over long distances. Additionally, it requires energy and may not ensure that the person is actually heard.

Staying quiet and waiting can lead to further dangers and a lack of visibility, which could delay rescue efforts. Hiding until help arrives is generally not advisable, as it may prevent the individual from being seen by rescuers, further increasing the risk of remaining undiscovered for a longer period.

In summary, using emergency flares maximizes the chance of being noticed and rescued in a survival situation, making it the best choice for signaling for help.
