Final answer:
Ceratosaurs are a group of early large predatory dinosaurs, and Dilophosaurus is the correct answer for a dinosaur included in Ceratosaurs. The other options provided, such as Tyrannosaurus and Allosaurus, are not ceratosaurs.
Step-by-step explanation:
Ceratosaurs are a group of theropod dinosaurs that were part of the larger clade Saurischia, the "lizard-hipped" dinosaurs. The correct answer to which dinosaurs are included in Ceratosaurs is B. Dilophosaurus. This genus is known for its distinctive double crest on its head and was one of the earlier large predatory dinosaurs from the early Jurassic period.
Other options provided, like Tyrannosaurus (A) and Allosaurus (D), are large theropods but not ceratosaurs. Dromaeosaurs (C), also known as raptors, are also not part of the Ceratosauria clade. Ceratosaurs are known from a variety of fossil remains and are an important group of early large predators in the dinosaur fossil record.
