Right option is (c) Exponentially with an increase in temperature

To elaborate: Thermistor is a device or resistor whose resistance is totally dependent on the temperature. Thermistor is widely applicable for several compensation techniques.

It exhibits variation in its resistance with respect to change in temperature. As the resistance of thermistor decreases with an increase in temperature, this property of thermistor is also regarded as negative temperature coefficient of resistivity.
