D.) He observed that individuals in a population generally displayed variation for a number of traits.

Explanation:

B) He proposed a mechanism to explain the process of evolution.

Explanation:

Charles Darwin's most significant original contribution to understanding both the unity and diversity of life is that he proposed a mechanism to explain the process of evolution. The mechanism that he proposed is called natural selection. Organisms that are able to adapt to the environment are more likely to survive and reproduce better than other organisms. They will leave more offsprings with their traits. These traits become more and more common over the years, as other organisms fail to survive. Charles Darwin explained the way species evolve by adapting to their environment.
