Answer
D. They involve changes in energy.**
Explanation
The observations from Georgina, Amy, Wilhelm, and Ron all involve changes in energy. Georgina observed a ball falling, which is a change from potential to kinetic energy. Amy noted that bonds between atoms change, which involves chemical energy changes. Wilhelm mentioned breaking an atomic nucleus, which releases nuclear energy. Ron observed heat transfer, which is a change in thermal energy. Therefore, the commonality among all observations is that they involve changes in energy.
