Solution

The correct option is A conductor; insulator
Substances that allow electric current to pass through them, are called conductors, while the ones that don't , are called insulators. Mercury is a good conductor of electricity because it is a (liquid) metal. Pure water has no free ions/electrons that help in conducting electricity, so it cannot conduct electricity, and hence, is an insulator.
