Solution
The correct option is A Coenozoic
The cenozoic era began about 65 million years ago and continues to the present. It is the third documented era in the history of Earth. The cenozoic era is also known as the 'age of mammals', because of the extinction of many groups of giant mammals, allowing smaller species to thrive and diversify, because their predators no longer existed. Hence, option A is the correct answer.
