The correct option is (b) The decrease in the number of species
 
For explanation I would say: ‘The Evil Quartet’ is the sobriquet used to describe the reasons for the decline in the number of species. The four reasons include Loss of habitat and fragmentation, Over-exploitation of species, Invasion of alien (new) species and Co-extinctions.
