Verified step by step guidance

1. Understand the concept of dehydration: Dehydration occurs when the body loses more fluids than it takes in, leading to an imbalance in electrolytes and water. Certain populations are more vulnerable due to physiological or lifestyle factors.
2. Evaluate why elderly individuals (I) are at risk: Aging reduces the sensation of thirst, kidney function declines, and there may be mobility or cognitive issues that limit fluid intake. These factors make elderly individuals more prone to dehydration.
3. Assess why individuals who menstruate (II) might be considered: Menstruation itself does not typically cause significant dehydration. However, if heavy menstrual bleeding occurs, it could lead to fluid loss, but this is not a primary risk factor for dehydration in most cases.
4. Analyze why infants (III) are at risk: Infants have a higher body water content, faster metabolism, and immature kidneys, making them more susceptible to fluid loss through diarrhea, vomiting, or inadequate fluid intake.
5. Combine the findings: Based on the analysis, elderly individuals (I) and infants (III) are the most at risk for dehydration due to their physiological vulnerabilities. Individuals who menstruate (II) are not typically at high risk unless specific conditions apply.
