Which of the following represent octahedral void ?

Options

A.
B.
C.
D.

Answer

To determine which of the given options represent octahedral voids, we need to understand the characteristics and locations of octahedral voids in a crystal lattice.

### Step-by-Step Solution:

1. **Understanding Octahedral Voids**:
- Octahedral voids are spaces in a crystal lattice where an atom can be placed. They are formed when atoms are arranged in such a way that they create an octahedral shape around the void.

2. **Locations of Octahedral Voids**:
- Octahedral voids are located at two specific positions in a crystal lattice:
- At the **body center** of the unit cell.
- At the **edge centers** of the unit cell.

3. **Analyzing the Options**:
- **Option 1**: If the diagram shows a void at the body center, this represents an octahedral void.
- **Option 2**: If the diagram shows voids at the edge centers, these also represent octahedral voids.
- **Option 3**: If the diagram shows a void at the face center, this does not represent an octahedral void.

4. **Conclusion**:
- Based on the analysis, the correct options that represent octahedral voids are:
- **Option 1** (body center)
- **Option 2** (edge centers)

### Final Answer:
The correct answers are **Option 1** and **Option 2**.
