Final answer:
The non-ceratosaurian theropods are the coelurosaurs, which is a clade that includes a wide range of species, including birds that evolved from this group of dinosaurs.
Step-by-step explanation:
The non-ceratosaurian theropods are the coelurosaurs (Answer B). Theropods are a diverse group of bipedal dinosaurs, and coelurosaurs is a clade that encompasses a wide range of species, including birds, which evolved from this group. Within the larger classification of theropods, two major divisions exist: the ceratosaurs and the non-ceratosaurian theropods.
Ceratosaurs include more primitive predatory dinosaurs like the Ceratosaurus, whereas the non-ceratosaurian theropods, specifically the coelurosaurs, encompass a more derived and diverse group. These include the tyrannosaurids, maniraptorans, and ultimately birds. This group exemplifies the evolutionary trend of theropods toward increasingly bird-like features, and includes some of the most intelligent and agile of the dinosaur groups.
