Question:
Given below are two statements
Statement I: The total water requirement for sedentary adult man and adult woman is 2500 ml
Statement II: Females have higher total body water than males due to their higher body fat content.
In light of the above statements, choose the most appropriate answer from the options given below

In light of the above statements, choose the most appropriate answer from the options given below
Show Hint
To remember: Fat tissue is hydrophobic and contains very little water.
Because women have a higher percentage of body fat than men, they have a lower percentage of total body water.
Because women have a higher percentage of body fat than men, they have a lower percentage of total body water.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Water is the most abundant chemical component of the human body, essential for temperature regulation, metabolic reactions, and solute transport.
Water requirements and total body water percentages vary based on age, gender, and body composition.
Step 2: Detailed Explanation:
Let us analyze the correctness of both statements:
Statement I: The average total water requirement (including fluids, drinking water, and water contained in solid foods) for a sedentary adult under normal environmental conditions is approximately 2,500 ml/day.
This matches standard physiological guidelines, which recommend a baseline fluid intake of 2 to 5 liters daily to balance standard water losses.
Therefore, Statement I is correct.
Statement II: Total body water (TBW) is inversely proportional to body fat percentage because adipose (fat) tissue contains significantly less water (approx. \(10\%\)) than lean muscle tissue (approx. \(75\%\)).
Because adult females typically have a higher body fat percentage and lower muscle mass than males, their TBW percentage is lower (approx. \(50\%\)) compared to males (approx. \(60\%\)).
The claim that females have a higher total body water percentage due to higher fat content is physiologically incorrect.
Therefore, Statement II is incorrect.
Step 3: Final Answer:
Statement I is correct, but Statement II is incorrect.
Water is the most abundant chemical component of the human body, essential for temperature regulation, metabolic reactions, and solute transport.
Water requirements and total body water percentages vary based on age, gender, and body composition.

Because adult females typically have a higher body fat percentage and lower muscle mass than males, their TBW percentage is lower (approx. \(50\%\)) compared to males (approx. \(60\%\)).
The claim that females have a higher total body water percentage due to higher fat content is physiologically incorrect.
Therefore, Statement II is incorrect.
Step 3: Final Answer:
Statement I is correct, but Statement II is incorrect.
