Question

Dinosaurs are

• A. Primitive amphibians
• B. Extinct reptiles
• C. Giant mammals
• D. Primitive mammals

Answer 1

The correct option is B Extinct reptiles

Dinosaur, the common name given to a group of reptiles, often very large, that first appeared roughly 245 million years ago (near the beginning of the Middle Triassic Epoch) and thrived worldwide for nearly 180 million years. Most died out by the end of the Cretaceous Period, about 66 million years ago, but many lines of evidence now show that one lineage evolved into birds about 150 million years ago.

Therefore, the correct answer is option b.
