The correct statement is: Heat will flow from the iron block to the water until both reach a temperature somewhere between 50 degrees Celsius and 250 degrees Celsius.
In this scenario, heat transfer occurs from the hotter object (the iron block at 250 degrees Celsius) to the cooler object (the water at 50 degrees Celsius). The final temperature will be somewhere between these two temperatures, depending on the masses and specific heat capacities of both the iron and the water.
