Which theory BEST describes how an asteroid striking Earth may have caused the extinction of dinosaurs?

• Heat from the asteroid caused massive fires that reduced the food supply.
• Dense clouds formed following the collision, causing a global drop in temperature.
• Land masses were altered by the collision, reducing the space where dinosaurs could roam for food.
• Glaciers melted rapidly from heat produced by the asteroid, causing floods that destroyed dinosaurs' habitats.
