The definition of a mineral is that it will contain a metallic substance. Coal is produced by pressure on carbon compounds and contains no minerals as such. Coal is Organic...It has a definte chemical compostion from peat to lignite to bituminous to antracite forms, it does not exist per se as a liquid but petroleum products such as crude oil do, they also exist in a gaseous state...so, in a sense coal or hydrocarbons can exist in a liquid form. However mercury is metallic and derived from a mineral but exists as a liquid state once purified. So the best answer is B

It doesn't meet the "mineral rules". Mainly, coal lacks a defined crytsal lattice and, as mentioned several times already, is organic (carbon-based), esentialy composed of decayed plants. Just because it is made of one element, does not necessarily preclude it being a mineral or not. For example, sulfur is a mineral.

I'd have to guess D though B also has a point but basically the same as D. Just being inorganic does not mean you are not mineral.
It is a product of nature that is to complex to be as 'simple' as a mineral.
