  • Statement (s ) : Populations of a species inhabiting different geographical areas are in a continuous process of adaptation to their surrounding environments and this leads to the evolution of species. Reason (R ) : Geographical barriers obstruct interbreeding of populations of a species leading to reproductive isolation and evolution of new species.

    Both (S ) and (R ) are not true
    B
    Only (S ) is true but not (R )
    C
