B.Room thermometers have a range from 30 ºC to 100 ºC.
C.Laboratory thermometers have a range from 35 ºC to 42 ºC.
D.The range of a laboratory thermometer is greater than that of a clinical thermometer.✓ Correct
Explanation
Laboratory thermometers typically have a range of -10°C to 110°C, while clinical thermometers have a small range of 35°C to 42°C. So the laboratory thermometer's range is much greater. Clinical thermometers cannot measure boiling liquids since they don't go above 42°C. The ranges in options 2 and 3 are swapped.
