Answer:
The insects.
Explanation:
Insects would be the organisms most likely to survive a bombardment or the impact of comets and asteroids. This is not due to the insects' body structure and composition, but because of their habits.
All insects have an exoskeleton formed by chitin. This subtlety does not promote resistance to chemicals and impacts as strong as that caused by asteroids and bombs. However, some insects have a habit of always hiding themselves in cracks in the walls, in drains, under objects etc. This ability is what would promote the survival of some insects. This is because, once "protected" they would have a better chance of surviving than the organisms that live on the surface of the earth, such as mammals.
Germany fought Russia/USSR and France in both world wars. Both Italy and Japan where aligned with Third Reich in WW2, but fought against Germany in WW1. Italy did align itself with the German Empire in the years leading up to WW1, so that is the best answer out of all of these. However none of them are truly correct.
