Which among the following varieties of coal possess the highest percentage of carbon?

Options

A. Peat
B. Lignite
C. Bitumen
D. Anthracite

Answer

To determine which variety of coal possesses the highest percentage of carbon, we can analyze the different types of coal and their carbon content. Here’s a step-by-step solution:

### Step 1: Understand the Types of Coal
Coal is classified into different types based on its carbon content and other properties. The main types of coal are:
1. Anthracite
2. Bituminous
3. Lignite
4. Peat

### Step 2: Identify the Carbon Content of Each Type
Next, we need to know the percentage of carbon in each type of coal:
- **Anthracite**: Contains approximately **90% carbon**.
- **Bituminous**: Contains approximately **70% carbon**.
- **Lignite**: Contains approximately **40% carbon**.
- **Peat**: Contains approximately **28% carbon**.

### Step 3: Compare the Carbon Content
Now, we compare the carbon content of these types:
- Anthracite: 90%
- Bituminous: 70%
- Lignite: 40%
- Peat: 28%

### Step 4: Determine the Highest Carbon Content
From the comparison, we can see that **Anthracite** has the highest percentage of carbon at **90%**.

### Conclusion
Thus, the variety of coal that possesses the highest percentage of carbon is **Anthracite**.
