A Thermistor

B Rheostat

C Potentiometer

D Photoconductive cell

ANS:A - Thermistor

temperature based resistor, NTC and PTC both are temperature based thermistor resistors it may be an NTC or PTC. Thermistors are two opposite fundamental types: 1) NTC- Negative Temperature Coefficient. If here temperature increases resistance decreases. 2) PTC- Positive Temperature Coefficient. If here temperature increases resistance also increases.
