Concept:A thermoelectric thermometer works by using the small electromotive force (e.m.f.) generated by a thermocouple to measure temperature.Explanation:It responds quickly, so it can measure rapidly changing temperatures.It has a wide working range, allowing it to measure both high and low temperatures.Its tiny junction enables temperature measurement almost at a single point.However, it is not fairly sensitive, because the thermoelectric e.m.f. produced for each degree change is very small.Therefore, high sensitivity is not one of its advantages.Answer:D. is fairly sensitive
