List I
List II
I. Diamond
A) Calcium
II. Marble
B) Silicon
III. Sand
C) Aluminium
IV. Ruby
D) Carbon
Codes:

Accepted Answer

The correct answer is D because of the following chemical compositions:

I. Diamond corresponds to Carbon. Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.

II. Marble corresponds to Calcium. Marble is a metamorphic rock composed primarily of recrystallized carbonate minerals, most commonly calcite or dolomite, which are forms of calcium carbonate.

III. Sand corresponds to Silicon. The most common component of sand is silica, also known as silicon dioxide, which is composed of silicon and oxygen.

IV. Ruby corresponds to Aluminium. Rubies are a variety of the mineral corundum, which is crystalline aluminium oxide. The red color is caused by the presence of the element chromium, but the base element is aluminium.

Therefore, the correct matching is I-D, II-A, III-B, and IV-C.
