Solution

The correct options are
B Habitat destruction
C Introduction of exotic species
Endemic (native) species are those which are found only in a particular region. Since they are confined only to a particular region, habitat destruction leads to their extinction. Introduction of new, exotic species creates competition for food and shelter. This puts great stress on the endemic species.
