Regarding the question about a clinical thermometer, the correct statement is:
B. Clinical thermometer bulb contains mercury that indicates temperature.
This statement is true because clinical thermometers indeed use a bulb containing mercury to measure and indicate temperature accurately. The expansion of the mercury in the bulb correlates with changes in temperature, allowing for an accurate reading. It is important to handle clinical thermometers carefully due to the presence of mercury, a toxic substance.
