Correct option is B
Explanation-
Dinosaurs -
Lived during the Mesozoic Era, which includes:
Triassic (250–201 million years ago)
Jurassic (201–145 million years ago)
Cretaceous (145–66 million years ago)
Angiosperms (flowering plants) -
First appeared in the early Cretaceous period. They co-existed with later dinosaurs
Option 2 correctly specifies "early diverging angiosperms", not modern ones (which evolved later)
Reptiles -
They are present since before the Mesozoic. Dinosaurs are reptiles, so of course reptiles were there
Amphibians -
Amphibians existed well before and throughout the Mesozoic. Frogs, salamanders, and their ancestors were all present alongside dinosaurs.
So, option b is correct because it includes:
Early angiosperms (accurate for late Mesozoic)
Reptiles (dinosaurs and others)
Amphibians (ancient group, present throughout)
These are all geologically accurate and would realistically appear in a dinosaur-era setting.
Incorrect options-
Option a: Includes humans, who appeared ~300,000 years ago, long after the dinosaurs went extinct (~66 million years ago)
Option c: Includes apes, who also appeared long after the Mesozoic
Option d: Excludes angiosperms, which were a major part of late Mesozoic ecosystems
