Question

# The pure form of carbon is found in:A. JuteB. DiamondC. Methane GasD. All of the above

Hint: We should be having an idea about the allotropes of carbon. Knowing the occurrence of the allotropes will help us to find the purest form of carbon. Think about the composition, chemical formulae and the sources of all the materials given in the options.

Note: Although methane does contain carbon atoms, the chemical formula of methane is $C{{H}_{4}}$, thus you can see that it contains 4 hydrogen atoms per carbon atom. Jute is a type of fibre that is made from the plant materials cellulose and lignin, which are complex compounds of carbon as well as other atoms.
