Answer : The correct option is, (D)
Explanation :
Vaporization process : It is type of process which occurs when phase changes from liquid phase to gaseous phase at constant temperature. And liquid converted to gas phase at temperature \(100^oC\).
Melting process : It is type of process which occurs when phase changes from solid phase to liquid phase at constant temperature. And solid converted to liquid phase at temperature \(0^oC\).
In the given diagram,
'A' shows the solid phase, 'B' shows the melting process, 'C' shows the liquid phase, 'D' shows the vaporization process and 'E' shows the gas phase.
Hence, the liquid is vaporizing at 'D' point.
