Answer:
The correct answer is C. co-evolution
Explanation:
When two or more species evolution is influenced by each other and are interdependent than this type of evolution is known as co-evolution. There are several examples of co-evolution like predator-prey co-evolution, flowering plants and pollinators evolution, etc.
The predator-prey evolution is famous in which there is selective pressure on prey to evolve to avoid getting hunted and the same pressure is on predator to evolve with prey so that they can get their food and survive. Therefore the correct answer is co-evolution.
I actually had a similar question on my test and this is the answer:
The reason the magnet loses its magnetic properties is is because when you drop the magnet or bump it against something, the domain can get bumped or dropped out of alignment.
Hoped this helped :)
