Answer
# Brief Explanations:
The widely - accepted theory among scientists for dinosaur extinction is the asteroid impact theory. An asteroid impact around 66 million years ago is thought to have caused massive environmental changes like dust clouds blocking sunlight, disrupting the food chain, and leading to the extinction of dinosaurs. Floods from storms, harmful genetic mutations, or the introduction of a predator are not the main causes supported by most scientific evidence.
