(B) The carbon cycle (also known as the $CNO$ cycle) is a process of stellar nucleosynthesis in which stars on the main sequence fuse hydrogen into helium. In this cycle,carbon nuclei act as catalysts. They facilitate the fusion process but are not consumed in the net reaction. Therefore,the carbon nucleus is regenerated at the end of the cycle.
