{'best quality coal': [1, 0, 0, 0], 'lignite': [3, 0, 0, 0], 'peat': [2, 1, 2, 2], 'highest grade': [1, 0, 0, 0], 'anthracite': [2, 1, 2, 1], 'bituminous': [1, 0, 2, 0]}
The correct answer is option 4, Anthracite. Anthracite is the highest grade and best quality coal. This type of coal is known for its high carbon content, low impurities, and high energy density. It has a high luster and burns with a clean flame. Anthracite coal is formed from the metamorphism of bituminous coal and is the result of intense pressure and heat over millions of years. It is a hard and dense coal that offers a high heat output and is often used for heating and power generation. It is important to note that the other options listed are not of the same high quality and grade as anthracite coal.
