Match List I with List II

List I		List II
A	Mesozoic Era	I	Lower invertebrates
B	Proterozoic Era	II	Fish & Amphibia
C	Cenozoic Era	III	Birds & Reptiles
D	Paleozoic Era	IV	Mammals

Choose the correct answer from the options given below :

To match the geological eras in List I with the corresponding dominant life forms in List II, let us analyze the characteristics of each era step-by-step:

1. Mesozoic Era (A): Known as the "Age of Reptiles," this era is famous for the rise and dominance of dinosaurs (reptiles). The first birds also evolved during this era. Therefore, A matches with III (Birds & Reptiles).

2. Proterozoic Era (B): This is an early geological era preceding the Cambrian explosion of complex life. The life forms during this time were primitive, consisting primarily of simple multicellular organisms and lower invertebrates. Therefore, B matches with I (Lower invertebrates).

3. Cenozoic Era (C): Often referred to as the "Age of Mammals," this is the current geological era. Following the extinction of the dinosaurs, mammals diversified and became the dominant terrestrial organisms. Therefore, C matches with IV (Mammals).

4. Paleozoic Era (D): This era is characterized by the rapid diversification of life, including the "Age of Fishes" (Devonian period) and the colonization of land by early amphibians. Therefore, D matches with II (Fish & Amphibia).

Combining these matches, we get:
A-III, B-I, C-IV, D-II

Comparing this result with the given choices, the correct option is:
A-III, B-I, C-IV, D-II
