Explanation:

A physical change is a change in the form or appearance of a substance without changing its chemical composition. A chemical change results in the formation of a new substance with different chemical properties. If substances mix and no new substance is formed, it's a physical change. If a new - substance is formed, it's a chemical change.

Answer:

We need more information about what happens in parts 2 and 3 (specifically what the changes in C and D are) to determine if it is a physical change, chemical change, or both. Without details about the nature of the changes in C and D, we cannot select an answer from the given options.
