Inorganic graphite is

Options

A. `B_(3)N_(3)H_(6)`
B. `B_(3)N_(3)`
C. `SiC`
D. `P_(4)S_(3)`

Explanation

To determine what inorganic graphite is, we need to analyze the options provided and understand the structure of boron nitride.

### Step-by-Step Solution:

1. **Understanding Inorganic Graphite**:
- Inorganic graphite refers to a material that has a structure similar to graphite but is composed of different elements. In this case, boron nitride (BN) is known to have a structure analogous to graphite.

2. **Identifying Boron Nitride**:
- Boron nitride can exist in various forms, but the hexagonal form (h-BN) is the one that resembles graphite. In this structure, boron and nitrogen atoms alternate in a hexagonal lattice, similar to how carbon atoms are arranged in graphite.

3. **Analyzing the Options**:
- The options provided include:
- (a) B3N3H6
- (b) B3N3
- (c) Incorrect option
- (d) Incorrect option
- We need to identify which of these represents inorganic graphite.

4. **Evaluating Each Option**:
- **Option (a) B3N3H6**: This compound is isostructural with benzene, but it is not what we refer to as inorganic graphite.
- **Option (b) B3N3**: This is the correct representation of inorganic graphite, as it indicates the hexagonal arrangement of boron and nitrogen atoms.
- **Options (c) and (d)**: These options are incorrect and do not represent inorganic graphite.

5. **Conclusion**:
- The correct answer is **B3N3**, which is the formula for inorganic graphite.

### Final Answer:
Inorganic graphite is represented by the formula **B3N3**.
