Solution

Correct option: (C)

Mercury is a liquid that can flow but does not stick to the glass.

Mercury is used in thermometers because It has a high coefficient of expansion so that even a small rise in temperature brings about sufficient expansion which can be detected in the capillary of the calibrated part of the thermometer.
