(D) According to the $NCERT$ textbook chapter 'Biodiversity and Conservation',all the given statements are correct. $1$. Evolution is a slow process,and the current rich biodiversity on Earth is the result of millions of years of evolutionary accumulation. $2$. Due to human activities,the rate of species extinction is currently much higher than the natural background rate. If this trend continues,we risk losing a significant portion of biodiversity within two centuries. $3$. Scientists have identified five mass extinction events in Earth's history,and the current rapid loss of species is widely considered to be the 'sixth extinction' caused by human impact.
