The human body is composed of approximately 65% water, making it the majority component of our bodies. While 50% (A) may seem like a large percentage, it is not enough to make up the majority. Similarly, 75% (C) and 80% (D) are significantly higher percentages and would result in a body that is more watery and less solid than it actually is. Therefore, B is the most accurate and scientifically accepted percentage for the amount of water in the human body.
