The correct answer is:
Cinnabar is a mineral and Limestone is a rock.
Explanation:
A limestone is a type of sedimentary rock, that is to say that it has been formed due to sediments that have been deposited and transported by wind or water, and that come from other rocks, in this case these sediments are debris from the ocean, and small pieces of seashells.
It is formed by a chemical compound called calcium carbonate and can be easily found in crystalline waters at shallow depth.
Cinnabar is a non-metallic mineral compound by chemicals that makes it dangerous for humans, which are 85% per mercury and 15% sulfur.
It is a mineral formed by different processes and substances found in hot water, and it has a shining red color.
Its formation is also in shallow waters and because they require hot water for its formation, it is common to see that these types of rocks form near places that have had active volcanoes recently.
