Options

A. Mixture of glyceryl nitrate and dinitrate absorbed on Kesielguhr.
B. Mixture of glyceryl dinitrate and trinitrate absorbed on Keiselguhr.
C. Mixture of glyceryl nitrate and trinitrate adsorbed on Keiselguhr.
D. All

Explanation

To determine what dynamite is, we will analyze the options provided and identify the correct components of dynamite.

### Step-by-Step Solution:

1. **Understanding Dynamite**: Dynamite is known as an explosive material. It was invented by Alfred Nobel in 1867 and is used in various fields, including construction and demolition.

2. **Components of Dynamite**: The main components of dynamite include nitroglycerin, which is a highly explosive liquid. It is often mixed with an absorbent material to stabilize it for safe handling.

3. **Analyzing the Options**:
- **Option 1**: Mixture of glyceryl, nitrite, and dinitrate absorbed on chiselgar.
- **Option 2**: Mixture of glyceryl, dinitrite, and trinitrite absorbed on chiselgar.
- **Option 3**: Mixture of glyceryl, nitrite, and trinitrite absorbed on chiselgar.
- **Option 4**: All of the above.

4. **Identifying the Correct Components**:
- The correct chemical composition of dynamite is primarily nitroglycerin, which can be referred to as glyceryl trinitrate (not dinitrite or nitrite).
- The absorbent material used is often diatomaceous earth, which is sometimes referred to as "chiselgar".

5. **Conclusion**: The correct option that accurately describes the composition of dynamite is **Option 2**: mixture of glyceryl (which refers to glyceryl trinitrate), dinitrite, and trinitrite absorbed on chiselgar.

### Final Answer:
**Option 2**: Mixture of glyceryl, dinitrite, and trinitrite absorbed on chiselgar.
