Answer:
D.) Extinction is not normal but only happens because of human influences.
Explanation:
Extinction is a state or phenomenon where a family or group of a particular species may all be extinct/ gone permanently. This event happens when the very last of any biological species is destroyed or removed or died, leaving no possibility of any future 'generation' to emerge.
Extinction is a permanent loss of the whole race/ species, with no offspring to continue the generation. It is also an irreversible process which means it cannot be reversed or taken back. It can and be local or global, can happen in all scales worldwide but it is not happening because of human interference. It can occur due to man made events but also at the same time, it can also happen due to the ecological, geological and biological issues.
