What should a diver do if they find themselves caught in a rip current?

Swim towards the current
Swim parallel to the shore until free
Stay still and float
Panic and shout for help

The correct answer is: Swim parallel to the shore until free

When a diver finds themselves caught in a rip current, swimming parallel to the shore until free is the appropriate course of action. Rip currents are powerful, fast-moving channels of water that flow away from the shoreline. Swimming directly against the current can be extremely challenging, and often futile, as the current can be stronger than the average swimmer's strength. By swimming parallel to the shore, a diver can effectively escape the narrow current's grip. Once they are outside the rip current's pull, they can then swim back to the shore, where they will find the conditions more manageable. This strategy is essential for conserving energy and preventing exhaustion or panic, which can lead to dangerous situations. Remaining still and floating could help conserve energy, but it does not provide a means to escape the current if it’s strong. Therefore, while floating may be a temporary option, it's not a solution for getting back to safety. Likewise, panicking or shouting for help is not a reliable or effective response, as it doesn't address the immediate need to escape the current and can lead to disorientation or increased risk in a dangerous situation. Being calm and using the correct technique is vital for safety when caught in such conditions.
