D. Conclusion
After gathering data in support of a hypothesis, you can make a conclusion.
A hypothesis has to be tested multiple times by multiple researchers to become a theory. A fact has to be proven multiple times as well (but theory is a much better word).
Explanation:
When gas molecules are heated, the molecules move more quickly, and the increased velocity causes more collisions. As a result, more force is exerted on each molecule and air pressure increases. Temperature affects air pressure at different altitudes due to a disparity in air density.
