As the air continues to cool during the night, the relative humidity will increase due to the fog. This means that the air is becoming moister. However, for the dew-point temperature to increase, the air would need to become drier. Therefore, the dew-point temperature will likely decrease as the air becomes moister. Choice D is the best choice.
