Solution
The correct option is B decreases As the temperature increases, the resistance of pure metals increases. This happens as the increased energy of the particles makes them vibrate faster which obstruct the flow of electrons.
Ionic solutions on the other hand get less viscous, the mobility of ions increases too as the temperature increases. This makes the resistance drop and the current increase.
