The correct response is:
Thermal energy will flow from the oven into the turkey until they reach equilibrium at 100°C.
Here's the reasoning behind this: When the turkey, which is at a higher temperature than room temperature, is placed in the oven with a temperature of 185°C, thermal energy will flow from the oven (the hotter object) into the turkey (the cooler object). Since the oven is turned off, it will not maintain its temperature indefinitely, but initially, the turkey will absorb heat from the oven until the temperatures start to equalize (reach thermal equilibrium). Given that the final equilibrium temperature will be somewhere between the initial temperatures of the turkey and the oven, it is reasonable to expect that they will stabilize at a temperature lower than the oven's initial temperature but higher than the turkey's initial temperature, likely around 100°C.
