How many days can an individual typically survive without water?

An individual can typically survive without water for about three to five days, although this can vary depending on several factors such as environmental conditions, physical activity levels, and individual health status. Therefore, the option indicating survival for a couple of days is considered the correct answer because it aligns with the widely accepted understanding that dehydration can set in rapidly, leading to severe physiological consequences.

While some people may survive a week under certain circumstances, the average survival timeframe without water emphasizes the critical importance of hydration. The longer durations suggested by the other options extend beyond the average time frame recognized in nutritional science and human physiology.
