keywords: 

{'lignite coal': [0, 0, 2, 0], 'peat coal': [0, 0, 1, 0], 'bituminous coal': [0, 1, 0, 0], 'anthracite coal': [0, 0, 1, 0], 'carbon': [1, 0, 4, 5], 'higher percentage': [0, 1, 1, 0]}

The correct answer is option 4, Anthracite coal.

To understand why, let`s examine the other options:

1. Lignite coal: Lignite coal is a type of coal that is low in carbon content and high in moisture. It contains around 25-35% carbon, making it lower in carbon content compared to anthracite coal.

2. Peat coal: Peat coal is the lowest grade of coal and is formed by the partial decomposition of vegetation. It has a carbon content of around 45-55%, which is higher than lignite coal but still lower than anthracite coal.

3. Bituminous coal: Bituminous coal is a widely used coal and is intermediate in carbon content. It typically contains around 60-80% carbon, which is higher than both lignite and peat coal, but still lower than anthracite coal.

4. Anthracite coal: Anthracite coal is the highest grade of coal and contains the highest percentage of carbon among the options. It generally contains over 90% carbon, making it the option with the highest carbon content.

Therefore, option 4, Anthracite coal, has the highest percentage of carbon among the given options.
