Final answer:
The daily recommended water intake is about 3.7 liters (15.6 cups) for adult males and 2.7 liters (11 cups) for adult females, including water from all dietary sources and the water produced by the body.
Step-by-step explanation:
The daily recommended water intake for both males and females is significantly higher than the options provided in the question. According to the Food and Nutrition Board of the Institute of Medicine (IOM), the Adequate Intake (AI) for water is about 3.7 liters (15.6 cups) for adult males and 2.7 liters (11 cups) for adult females. It's essential to consider that this includes water from all dietary sources, not just the water we drink. This means that water found in beverages and water content from foods are taken into account. It is also worth noting that the body naturally produces some water through metabolic processes and that water is lost through various means such as urination, perspiration, and breathing.
