    A a thermometer which can be used to measure very high and very low values of temperature
    B a thermometer which gives the same increase in length of the liquid column for each degree of temperature rise
    C a thermometer which is accurate because it has been calibrated
    D a thermometer which gives a large increase in the length of the liquid column for each degree of temperature rise
