(A) Devonian
(B) Jurassic
(C) Tertiary
(D) Cretaceous
(E) Tail of rabbit

Answer 1

Hint:The Palaeozoic also known as Palaeozoic is the earliest and large era of three geologic eras of Phanerozoic Eon. It lasted from 541 60 251.902 million years ago, and is subdivided into six geologic periods.

Complete answer:
The planet contains different layers of sediments, of which the underside layer is the oldest and therefore the upper layer is the most up-to-date layer. supported the age of rocks, a continuance was prepared and it's called the geologic time scale, it depicts the various stages of the evolution of life on the planet over the past countless years. It consists of three Eons that consists of Eras which are divided into Periods that will be further subdivided into Epochs. These Eras, Periods, Epochs depict the time of origin and also the dominance of the certain group of animals during certain Eras or Periods. It provides the foremost evidence for the concept of evolution.
So as from oldest to youngest, the three Eons are as follows:
- Archean Eon: ancient or archaic (oldest rocks on earth).
- Proterozoic Eon: This is the eon of beginning of life (2.5 billion to 542 million years ago).
- Phanerozoic Eon: during this, visible life exists (542 million years ago to present).
These are eras within the Phanerozoic. so as from oldest to youngest, they're as follows:
(i) Precambrian Era: it's the earliest part of earth’s history.
(ii) Paleozoic Era: it's the traditional life (such as trilobites).
(iii) Mesozoic Era: it's the center life ( dinosaurs).
(iv) Cenozoic Era: it's the recent life ( like mammals and flowering plants).
From the above discussion it will be concluded that Devonian is part of the geological era.
So, the right answer is option A.

Note:- The Devonian period occurred from 416 million to 358 million years ago. It absolutely was the fourth period of the geological era. It absolutely was preceded by the Silurian period and followed by the Carboniferous period.
