Solution

The correct option is B $C a m b r i a n \to O r d o v i c i a n \to S i l u r i a n \to D e v o n i a n \to C a r b o n i f e r o u s \to P e r m i a n$
Palaeozoic era is the era of ancient life. The correct arrangement of periods of this era is $C a m b r i a n \to O r d o v i c i a n$ (age of invertebrates) $\to S i l u r i a n \to D e v o n i a n$ (age of fishes) $\to C a r b o n i f e r o u s$ (age of Amphibians) $\to P e r m i a n$ .
