Given below are four statements (i) - (iv) regarding geological time s...
Explanation:

The given statements are as follows:

(i) Palaeozoic era is the era of ancient life
(ii) Ordovician period is the age of vertebrates
(iii) Carboniferous period is the age of reptiles
(iv) Proterozoic era is the era of early life

We need to identify the incorrect statements among the given options.

Incorrect statements:

To determine the incorrect statements, let's analyze each statement one by one.

(i) Palaeozoic era is the era of ancient life
- This statement is correct. The Palaeozoic era, also known as the "era of ancient life," spans from about 541 to 252 million years ago. It is characterized by the diversification of many major animal groups.

(ii) Ordovician period is the age of vertebrates
- This statement is incorrect. The Ordovician period, which occurred from about 485 to 443 million years ago, is not specifically known as the age of vertebrates. Vertebrates first appeared during the Cambrian period, which is an earlier geological period.

(iii) Carboniferous period is the age of reptiles
- This statement is incorrect. The Carboniferous period, which took place from about 358 to 298 million years ago, is known for the abundance of plants and the formation of extensive coal deposits. Reptiles emerged during the subsequent period, known as the Permian period.

(iv) Proterozoic era is the era of early life
- This statement is correct. The Proterozoic era, which lasted from about 2.5 billion to 541 million years ago, is often referred to as the era of early life. It encompasses significant geological and biological events, including the development of eukaryotic cells and the appearance of multicellular organisms.

Conclusion:

Based on the analysis of each statement, it can be concluded that the incorrect statements are:

- (ii) Ordovician period is the age of vertebrates
- (iii) Carboniferous period is the age of reptiles

Hence, the correct answer is option B) (ii) and (iii).
