The necessary precautions that must be taken when using thermometer include the following: make sure the liquid inside the thermometer is at eye level when taking taking the temperature and make sure the bulb of the thermometer does not touch the bottom of the beaker when taking the temperature.
Never use a thermometer as a stirring device, don't swing or shake down a thermometer and make sure the bulb of the thermometer is surrounded on all sides by the liquid which is to be measured.

Temperature is a physical attribute of any object that tells about the coldness or hotness of the substance or the object. It is measured using a thermometer and in Kelvin or degrees Celsius.

The following are the ways to ensure accurate readings:

  • Option B. Make sure the liquid inside the thermometer is at eye level when taking the temperature.

  • Option C. The bulb of the thermometer does not touch the bottom of the beaker or ice when taking the temperature.

The ways can be explained as:

  • One should never shake or stir using a thermometer as it can destroy the mercury of the meter.

  • The readings should be noted at eye level so that any error can be avoided. Eye-level readings are accurate and have fewer chances of getting errors.

  • The base of the bulb of the thermometer should not touch the base of the beaker or ice as it will alter the readings.

  • Measuring temperature in Fahrenheit or Celsius scale does not affect readings as they are just units for measurements.

Therefore, options B and C are correct.
