(A) The process of heating ice from $-10\,^oC$ to steam at $100\,^oC$ involves several stages:$1$. Heating ice from $-10\,^oC$ to $0\,^oC$: The temperature increases linearly with heat supplied.$2$. Melting ice at $0\,^oC$: The temperature remains constant at $0\,^oC$ as phase change occurs.$3$. Heating water from $0\,^oC$ to $100\,^oC$: The temperature increases linearly with heat supplied.$4$. Boiling water at $100\,^oC$: The temperature remains constant at $100\,^oC$ as phase change occurs.Thus,the temperature-heat graph should show two regions of increasing temperature separated by two horizontal plateaus. Graph $A$ correctly depicts this behavior.

$A$ block of ice at $-10\,^oC$ is slowly heated and converted to steam at $100\,^oC.$ Which of the following curves represents the phenomenon qualitatively?
