Solution

The correct option is B decreases
The resistance of the conductor increases with the rise in temperature, because temperature coefficient of resistance for conductor is positive but for semiconductors the temperature coefficient of resistance is negative. hence resistance is indirectly proportional to temperature.
due to that resistance decreases with increase in temperature.
