Which of the following is a three dimensional silicate

Options

A. Mica
B. Spodumene
C. Zeolite
D. None of these

Explanation

To determine which of the given options is a three-dimensional silicate, we can follow these steps:

### Step 1: Understand the Types of Silicates
Silicates can be classified based on their structural arrangement:
- **1D silicates**: Chains of silicate tetrahedra.
- **2D silicates**: Sheets of silicate tetrahedra.
- **3D silicates**: Three-dimensional frameworks of silicate tetrahedra.

### Step 2: Identify the Given Options
Assuming the options provided include various silicate minerals or compounds, we need to evaluate each one to determine its structure.

### Step 3: Analyze Each Option
- **Micah**: This is a phyllosilicate (sheet silicate), which means it has a 2D structure.
- **Spodumene**: This is a chain silicate (inosilicate), which means it has a 1D structure.
- **ZSM-5**: This is a zeolite, which is known for its three-dimensional framework of silicate tetrahedra.

### Step 4: Conclusion
Based on the analysis, the only option that represents a three-dimensional silicate is **ZSM-5**.

### Final Answer
The three-dimensional silicate among the options is **ZSM-5**.
