The answer is B. The water conducts the heat from the iron ball and thus WATER'S temperature will increase while the temperature of the ball will constantly keep decreasing as it is loosing heat. After sometime both the water and the ball come to equilibrium state i.e they have the same temperature. From then on the temperature will remain constant. AS graph in option B indicates an increase in temperature for a while and then constant temp it is correct
