Impulse is change in momentum due to collision.
Largest change occurs for condition B, where change is twice the original momentum. Result is up. Damage is due to work done on the car as it is smushed. The force on each of the cars will be the same due to Newton's third law, and the degree of damage is characterized by how far the car's front end has been smashed. Since these are identical cars, the same average force gives the same damage.
