The best interpretation of the two flat portions of the graph is:
**D. These show where changes of state are occurring.**
In a temperature vs. heat added graph, the flat portions typically represent phases where a substance is undergoing a change of state, such as melting or boiling, during which the temperature remains constant until the phase change is complete.
