• A. Extinction rate
• B. Massive extinction rate
• C. Background extinction rate
• D. All of the above

Answer 1

The correct option is C Background extinction rate

Background extinction occurs when species go extinct at a natural rate. This happens when the species are subjected to natural selection and evolution, causing some species to go extinct and resulting in the survival of the fittest. Apart from these, natural disasters are also reasons for the loss of biodiversity.
