Habitat loss and fragmentation: This is the most important cause driving animals and plants to extinction.$2$. Over-exploitation: Humans have over-exploited many species (e.g.,Steller's sea cow,passenger pigeon) for food or commercial needs.$3$. Alien species invasion: When alien species are introduced unintentionally or deliberately,some of them turn invasive and cause the decline or extinction of indigenous species.$4$. Co-extinction: When a species becomes extinct,the plant and animal species associated with it in an obligatory way also become extinct.Since all four listed factors $(a, b, c, d)$ are recognized causes of biodiversity loss,the correct answer is $4$.
