Solution

The correct option is B (I)-r, (II)-s, (III)-s, (IV)-r
(I) Series contains all eons and the odd one is Palaeozoic era.
(II) Series consists of periods of the Palaeozoic era and the odd one is Cretaceous period which belongs to Mesozoic era.
(III) Series consists of epochs of the Tertiary period of Cenozoic era . However, Permian is a period belonging to the Palaeozoic era.
(IV) Series consists of the eras of the Phanerozoic eon and the odd one is Jurassic period which belongs to the Mesozoic era.
