Solution

The correct option is D Both statements are incorrect.
Mercury is preferred as a liquid in thermometers because:
1. Its expansion is uniform.
2. It is opaque and shiny.
3. It does not stick to the sides of the glass tube.
4. It is a good conductor of heat.

Also, advantage of using alcohol in a thermometer is that the expansion per degree celsius of alcohol with respect to mercury is more.
Therefore, both the given statements are incorrect.
