Based on the question and the provided options, the best response would likely be:
d. Humans are composed primarily of water.
This is a widely accepted fact that the human body is largely made up of water, typically around 60% to 70% of an adult's body weight. While other elements are important, the predominance of water is a critical aspect of human biology and would likely be supported by most biological data.
