In oxygen-containing atmospheres, the graphite readily converted into carbon dioxide at temperatures of 700oC and above.

When graphite is exposed to an atmosphere that contains oxygen, it undergoes a chemical reaction called oxidation, which results in the formation of carbon dioxide \left ( CO_{2} \right ).
 

The chemical equation for this reaction is:
C\left ( graphite \right )+O_{2}\rightarrow CO_{2}

In this reaction, carbon (C) from the graphite combines with oxygen (O_{2}) from the atmosphere to form carbon dioxide (CO_{2}).

Therefore, the correct answer is option b) Carbon Dioxide.
