A thermistor is suitable for :
Answer: C
A thermistor is suitable for low span but high sensitivity.
A thermistor's resistance changes by several percent per degree, much more than a metal resistance thermometer's, so it is very sensitive. But its resistance-temperature relation is strongly non-linear (exponential), and its usable range is limited to a few hundred degrees, so its span is small.
High span with low sensitivity describes thermocouples or platinum resistance thermometers better. A device with both high span and high sensitivity, or with both low, does not describe the thermistor's characteristic trade-off.
