Best answer
The correct answer is (a) Exponentially with an increase in temperature

Best explanation: Thermistor is widely applicable for several compensation techniques. It exhibits variation in its resistance with respect to change in temperature. As the resistance of the thermistor decreases with an increase in temperature, this property of thermistor is also regarded as negative temperature coefficient of resistivity.
