The correct option is B Cambrian $\to$ Ordovician $\to$Silurian $\to$ Devonian $\to$Carboniferous$\to$ Permian

A geologic time scale is natural advancement is the event of homologous and minimal organs. Homologous organs are those which have the regular inception and are based on a similar central example yet they perform diverse capacities and have distinctive appearances, e.g. whale's flipper, bat's wings, feline's paws, steed's front legs, fledgling's wings, bull's front legs, and human hands.

So, the correct option is 'Cambrian → Ordovician →Silurian → Devonian →Carboniferous→ Permian'.
