The BEST explanation for the absence of temperature increase between lines AB and CD is:
**The energy demand during a phase change is substantial enough to keep the temperature constant.**
During phase changes (like melting or boiling), the energy added to the substance is used to change its state rather than increase its temperature. This is why the temperature remains constant during these phases despite energy input.
