Answer:
B. mutations

I believe this is the answer because even though mutations can be bad, there are also good as they can provide genetic variation to a population, which can result in the trait being passed to the offspring. 
 
        
                    
             
        
        
        
Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.  
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.

Answer:
Erysipelothrix rhusiopathiae
Explanation:
Erysipelothrix rhusiopathiae is a Gram-positive, catalase-negative, rod-shaped, non-spore-forming, nonacid-fast, nonmotile bacterium. Distributed worldwide, E. rhusiopathiae is primarily considered an animal pathogen, causing the disease known as erysipelas that may affect a wide range of animals.
