The correct option is: (B)

Explanation:

Diamond is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centred cubic crystal structure called a diamond lattice.

The most common constituent of sand is silica (silicon dioxide, or SiO2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness is the most common mineral resistant to weathering.

Marble is composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).

Ruby is a pink to a blood-red-coloured gemstone, a variety of the mineral corundum (aluminium oxide).
