What argument that describes the cause of the Cretaceous mass extinction is best supported by the evidence?

Group of answer choices

Evidence of ash and heightened CO2 levels in rock strata formed at the time of the extinction event is evidence that volcanic activity increased global temperatures and reduced the availability of nutrients.

Heightened levels of oxygen in the soil shows that the environment was able to support large predators for the first time, wiping out many vulnerable species.

The presence of iridium, which is not common on earth, in rock strata that correspond to that time period indicates that a massive meteorite hit the earth.

An increase in the diversity of mammal species in the fossil record following the cretaceous mass extinction demonstrates that those species were able to outcompete the dinosaurs and drive them to extinction.
