The correct answer is Meteorites struck the region that Mexico now occupies.
The Cretaceous–Paleogene was a sudden mass extinction that took place approximately 66 million years ago. This event killed almost three quarter of the plants and animals species on earth. Almost all the animals were killed in this event weighing more than 25 kilograms. It was caused because of the impact of the comet and asteroid which destructed the global environment. Iridium was found in large amount in earth's crust, which is not a component of earth's crust. It is found in asteroids in huge amount.
Hence, when meteorites were not involved in the process then how come the meteorites get stuck in the region that now occupied as Mexico.
