Step-by-Step Verified Solution

Temperature of liquid oxygen will first increase in the same phase. Then, the liquid oxygen will change to gaseous phase during which temperature will remain constant, After that temperature of oxygen in gaseous state will increase. Hence option (a) represents corresponding temperature-time graph.
