Answer 1

The correct option is D

The given table gives the correct sequence and driving forces for the waves of extinction. The first wave was hunting, which was needed to satisfy hunger. The second wave of extinction was agriculture. This started when humans settled down and started a civilisation. The third wave of extinction was the harnessing of fossil fuels due to rapid industrialisation.
