Dear student,
The image of your question is truncated and it cannot be understood which questions are 2,3 and 4.

Answering what i have understood from the image.

1. There are three forms of pure carbon: Graphite, Coal and Diamond. All three are made up of elemental carbon, coal is the least pure when found in nature. Diamond is the purest form of Carbon, however all have some impurities when found in nature.

2. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace
3. Petroleum is also known as Black Gold - because when crude oil is extracted from the land it is black in colour. People call it gold because of its oils and value . It is very difficult to find.
