Hint:
Minerals are the natural substances which occur in nature in Various forms. Mineral refers to a bulk solid geologic material that is homogeneous at a large scale.

Complete Answer:
In geology or mineralogy, minerals can be defined as a solid chemical compound with a specific crystal structure that occurs in pure form in nature. minerals may occur in the cracks, faults, crevices, or joints of the metamorphic and igneous rocks. Major metallic minerals such as copper, zinc, tin, lead and many more are obtained from the rock. In simple terms, a rock can be stated as an aggregate of two or more minerals. Bauxite is a type of mineral which is formed by the decomposition of surface rocks, and the removal of soluble constituents. Ores are natural forms of minerals that have a high concentration of a certain element, usually a metal. Some of the examples of ores are cinnabar (HgS) an ore of Mercury, colemanite an ore of boron, sphalerite (ZnS) an ore of zinc. Ores are mined, treated and sold at a profit. Depending upon the concentration of the desired material it contains the grade of ore referred. Ores must undergo the process of extraction in order to extract the elements of interest from the waste rock. Ore genesis refers to the geological process through which ores are formed. Therefore, ores are the natural forms of minerals.

So, option A is the correct option.

Note:
Minerals occur in various forms in nature. Gems are an example of minerals that have ornamental values. Some examples of gems are ruby and sapphire. Mineraloids refers to the natural solid substances that lack definite crystalline structure. Some examples of mineraloids are opal and obsidian.
