The answer is the second one: More than 50%.

Explanation:

  • Oxygen is a major component of the human body, primarily because it is a significant part of water (H2O), which makes up a large portion of the body's mass. Additionally, oxygen is a component of many organic molecules in the body.
  • On average, oxygen constitutes about 65% of the human body by weight. This is because water accounts for approximately 60% of the body weight, and oxygen is a major element in water.
  • Therefore, the correct answer is that more than 50% of the body weight is made of oxygen.
