Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Earth's history is divided into geological eras based on the dominant life forms present during those times.
Step 2: Meaning
An "age" refers to the period when a specific group of organisms reached its maximum diversity and dominance.
Step 3: Analysis
The Palaeozoic era is the age of invertebrates and amphibians. The Cenozoic era is the age of mammals. The Mesozoic era (comprising Triassic, Jurassic, and Cretaceous periods) was dominated by dinosaurs and diverse reptiles.
Step 4: Conclusion
The Mesozoic Era is universally recognized as the 'Golden Age of Reptiles' due to their planetary dominance across land, sea, and air. Final Answer: (B)
