During the biosynthesis of brassinosteroid derived from the sterol campesterol follows two types of the pathway
i) Late C-6 oxidation pathway
ii) Early C-6 oxidation pathway
follows  the different reaction performing in each  pathways such as,
a) Campesterol → Campestanol →6-Deoxoteasterone→ Castasterone→Teasterone →Brassinolide
b) Campesterol → 6-Oxocampestanol →Cathasterone →Teasterone → Castasterone →Brassinolide
c) Campesterol → Campestanol →6-Deoxocathasterone →6-Deoxoteasterone → Castasterone →Brassinolide
Find the correct combination of the each oxidation pathway with its performing sequences;
