Verified step by step guidance1
Understand that total body water (TBW) is the percentage of a person's body weight that is made up of water. This varies with age, sex, and body composition.
Recognize that newborn infants have a higher percentage of total body water compared to adults. This is because infants have less fat and more water content in their bodies.
Consider that as people age, the percentage of body water decreases. Elderly individuals typically have a lower percentage of body water due to increased body fat and decreased muscle mass.
Note that adult males generally have a higher percentage of body water than adult females. This is because males typically have more muscle mass, which contains more water than fat tissue.
Conclude that among the given options, a newborn infant would have the highest percentage of total body water due to their body composition and developmental stage.
