The correct order of epochs in the Tertiary period from youngest to oldest is accurately represented in the selected choice.

To understand this, it is important to recognize the sequence of the epochs within the Tertiary period, which is a subdivision of the Cenozoic Era. The Tertiary period includes five primary epochs: the Paleocene, Eocene, Oligocene, Miocene, and Pliocene. When arranged chronologically starting from the youngest, the order is Pliocene, Miocene, Oligocene, Eocene, and finally, Paleocene.

This arrangement reflects the actual geological timeline as established by stratigraphic records and the fossil evidence that characterizes each epoch. The Pliocene is the most recent, followed by the Miocene, then the Oligocene, the Eocene, and the oldest of these epochs, the Paleocene.

Understanding the chronological order of geological time is essential for interpreting Earth's history and the evolution of life.
