True or False: The average woman contains more water than the average man pound-for-pound.

The average woman contains less water than the average man pound-for-pound. This is primarily due to physiological differences between the sexes. Men typically have a higher muscle mass compared to women, and muscle tissue contains more water than fat tissue. As a result, men generally have a higher percentage of body water compared to women, leading to the conclusion that, on average, women do not contain more water than men when comparing them on a pound-for-pound basis.

While the other options might seem plausible in certain contexts, they do not accurately reflect the general biological composition that dictates body water content between genders. Age can affect body water percentage, but it does not specifically address the average differences between men and women. Similarly, while pregnancy does alter a woman's body composition and water retention, this is not a factor in the basic comparison of average body water content between genders.
