B. Reptiles gave rise to birds during Jurassic period
C. It was a flying reptile in the Triassic period
D. Reptiles gave rise to birds during the Permian period.

Answer 1

Archaeopteryx is a genus of burden like dinosaurs that were the transitional link between non avian feathered dinosaurs and modern birds.

Complete step by step answer:
Archaeopteryx is considered to be the transitional link between non-avian dinosaurs and modern birds. They had both reptilian as well as avian features that led them to be the connecting link between the two. It was discovered in 1860, in Germany.
Archaeopteryx was found to be from the late Jurassic period, about 150 million years ago. They had similarities with small mesozoic dinosaurs and modern birds. Although the inclination was towards the dinosaurs. Jaws with sharp teeth, hyperextensible second toes, three fingers with claws, a long bony tail, feathers suggestive of warm-bloodedness, and various features of the skeleton showed a mixture of the two genera of animals.
Evolutionarily they prove that reptiles give rise to birds.
Since the Archaeopteryx belonged to the Jurassic period, option B is the correct answer.

Note: Permian, Triassic and Jurassic periods belong to the Mesazoic era. The Triassic period was the shortest of them all.
