D

Solution

The correct option is D Minerals

B. Minerals

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, resistance to tarnish, and its many special properties - some of which are unique to gold. Its rarity, usefulness, and desirability make it command a high price. 

The term mineral is sometimes used in reference to natural earth (non-living) resources, and thus, in a non-scientific sense, petroleum resources are mineral resources and deposits of petroleum are often called mineral deposits. Coal, sands, gravel, and such would also be considered a mineral resource in this particular usage, even though coal is a rock, not a mineral, and the others are mixes of multiple minerals and/or rocks and not, strictly speaking, minerals.
