Quartz is an example of

Options

A. Chain silicate
B. Sheet silicate
C. Cyclic silicate
D. Three dimensional network silicate

Explanation

**Step-by-Step Solution:**

1. **Understanding Quartz**: Quartz is a mineral composed of silicon and oxygen, with the chemical formula SiO₂. It is one of the most abundant minerals in the Earth's crust.

2. **Types of Silicates**: Silicates can be classified into different categories based on their structure:
- Chain silicates: These have a linear arrangement of silicate tetrahedra.
- Sheet silicates: These consist of two-dimensional sheets of silicate tetrahedra.
- Cyclic silicates: These have a ring structure of silicate tetrahedra.
- Three-dimensional (3D) network silicates: These have a three-dimensional framework of silicate tetrahedra.

3. **Analyzing Quartz's Structure**: Quartz has a three-dimensional network structure where each silicon atom is bonded to four oxygen atoms, and these tetrahedra are interconnected in a three-dimensional framework.

4. **Conclusion**: Based on this structural analysis, we can conclude that quartz is an example of a three-dimensional network silicate.

**Final Answer**: Quartz is an example of a three-dimensional network silicate.
