b. Asia, Jurassic Period
c. Asia, Early Cretaceous Period
d. Europe, Cretaceous Period

Answer 1

Ceratopsians first appeared in Asia during the Early Cretaceous Period, which is option c.

Step-by-step explanation:

Ceratopsians, a group of herbivorous dinosaurs known for their distinctive horns and frills, first appeared during the Late Jurassic to Early Cretaceous periods. However, they became more widespread and diverse during the Cretaceous Period, which lasted from about 145 to 66 million years ago. The earliest known ceratopsians are from Asia, but they later spread to other continents including North America, where they greatly diversified. Based on the provided options and the fact that ceratopsians were present in Asia before they were found in North America, the most accurate answer is c. Asia, Early Cretaceous Period.
