If temperature increases, resistance value decreases hence it is negative temperature coefficient.

Thermal + resistor = thermistor.
Here thermal indicate that resistor is temperature coefficient.
When temperature increase resistance decrease.

Thermistor is temperature sensing device.

Note that the question is which one is designed to be sensitive to temperature. And it is thermistor. i.e. , it is designed with the motto to be temperature Sensitive.
However the others may have the sensitivity with temp in practical cases. But they not intendedly designed to be sensitive.

Thermistor is a kind of resistor depends upon the coefficient it provides resistance.
1. PTC- if temperature is increased resistance also increases.
2. NTC- if temperature is increased resistance also decreases.

Thermistor has negative temperature coefficient.

Thermistor is device designed specially to measure temperature. Hence it is a temperature sensitive component.

Thermistor has two type.
PTC Thermistor "POSISTOR" (for heaters, motor starters, over current protection, over heat sensing & automotive).
NTC thermistor (for inrush current suppression, temperature sensor / compensation & automotive) are offered.
Thermistor is a temperature measuring device.
