Cinnabar is a bright red mineral that consists of mercury sulfide (HgS). It is the single most vital ore of mercury, which is why option 1, mercury, is the correct answer.

Option 2, zinc, is incorrect. Zinc is primarily obtained from the mineral sphalerite, which is a sulfide of zinc.

Option 3, copper, is also incorrect. Copper is typically extracted from minerals like chalcopyrite, azurite, or malachite, not from cinnabar.

Lastly, option 4, lead, is incorrect as well. Galena is the primary ore of lead, not cinnabar.

So, the main point to understand here is that different metals are typically extracted from specific ores or mineral types - in the case of mercury, this primary ore is cinnabar.
