Explanation:

The Cenozoic era starts after the end of the Cretaceous. It is marked by the global mass extinction event known as the Cretaceous-Tertiary (K-T) boundary. The Cenozoic era started from about 65 million years back to the recent.

The new species started to evolve from the start of this era and there were abundant land animals during this era, and so this era is often regarded as the age of mammals. This is the most recent era in the geological time scale and is marked by the diverse group of organisms that has appeared after a long evolutionary process.

The Cenozoic era is again divided into three parts-

1) Tertiary- It is divided into (a) Palaeogene, (b) Eocene, and (c) Oligocene

2) Neogene- It is divided into (a) Miocene and (b) Pliocene

3) Quarternary- It is divided into (a) Pleistocene and (b) Holocene

Thus, the correct answer is option (D).
