B

It expands or contracts with temperature


D

All of the above


Mercury, being a metal is a good conductor of heat and remains liquid at room temperature and can flow. So, as the temperature of mercury increase, it expands and the length of the mercury column increase. Also, it is shiny (so easily visible) and does not stick to the walls of test-tube and multiple readings can be taken in a short time.
