Answer : 2. "increases"
Explanation :

At high temperatures, the tungsten filament gets hot and atoms in the filament vibrate more. The electrons in the current now collide more with the atoms & more energy is needed to push the current through the filament. Hence, the resistance of tungsten increases with temperature.
