the answer is A. If you heat a system then that is obvious that its temperature will rise, how can it remain the same when it is heated up. if SOF Olympiad says the answer is C then it has to give a better solution with more examples so that we can understand it better.

PQ shows the time taken by the ice to melt into water. Here, the temperature is steady – at 0°C. QR shows the time taken by the melted water to heat up and reach boiling point. Here, the temperature rises to boiling point – from 0°C to 100°C. RS shows the time taken by the water to evaporate. Here again, the temperature is steady – at 100°C. Part PQ shows melting of ice.Hence, the right answer is Option A.
