The correct answer is option 1 - Anthracite.

Anthracite coal is the variety of coal that has the highest amount of carbon in it. It is considered the highest-grade coal due to its carbon content, which can range from 86% to 98%. This high carbon content makes Anthracite coal highly efficient and produces a high amount of heat when burned.

Option 2 - Bituminous coal, also known as soft coal, has a lower carbon content compared to Anthracite. It typically contains around 45% to 86% carbon.

Option 3 - Lignite is a lower-grade coal with a relatively low carbon content ranging from 25% to 35%.

Option 4 - Peat is the lowest-grade coal, with the lowest carbon content. It is partially decayed plant material and contains around 60% to 75% water and less than 60% carbon.

Therefore, among the given options, Anthracite coal contains the highest amount of carbon.
