The evidence supporting the extinction of dinosaurs by an asteroid collision is rare metal on Earth called Iridium is found in layers where dinosaurs disappeared (option C)

Approximately 66 million years ago (end of the Cretaceous) an asteroid collided in the Earth's crust, extinguishing 75% of the species on Earth.

At the end of the 20th century, the crater from the asteroid collision was discovered. This was verified by the presence of a thin layer of sediment called the K – Pg boundary. This layer has the peculiarity that it shows unusually high levels of Iridium, a common element in asteroids.
