Choose the higher form of Carbon from the following:
(i) Graphite
(ii) Diamond
(iii) Buckminster fullerine
(iv) Bauxite

Options

A. (i), (ii) and (iii)
B. (ii), (iii) and (iv)
C. (i), (iii) and (iv)
D. (i), (ii) and (iv)

Explanation

To determine the higher form of carbon from the given options, we need to analyze each one based on their properties and structure.

### Step 1: Understand the Forms of Carbon
Carbon exists in several allotropes, which are different structural forms of the same element. The common allotropes of carbon include graphite, diamond, and fullerene.

### Step 2: Analyze Each Option
- **Graphite**: This is a form of carbon where the atoms are arranged in layers. It is known for its lubricating properties and conductivity.

- **Diamond**: This is another allotrope of carbon where each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, making it extremely hard and giving it a high melting point.

- **Buckminsterfullerene**: This is a molecular form of carbon that consists of 60 carbon atoms arranged in a spherical structure resembling a soccer ball. It has unique properties and is considered a form of carbon.

- **Bauxite**: This is not a form of carbon; it is an ore from which aluminum is extracted. Therefore, it does not belong to the category of carbon allotropes.

### Step 3: Determine the Higher Form
Among the options, diamond is often considered the "higher" form of carbon due to its hardness and the strength of its carbon-carbon bonds. While graphite and fullerene have their unique properties, diamond is typically regarded as the most superior form in terms of hardness and structural integrity.

### Conclusion
The higher form of carbon from the given options is **(ii) Diamond**.
