B)  Not only is the general concept of evolution not debated among most scientists, but there is unanimous acceptance of natural selection as the most important mechanism of evolution.

Explanation:

Nearly 97% of the scientific community holds evolution as the prevailing scientific theory about biological diversity. Intelligent design theories that challenged evolution have been refuted over and over by scientific institutions. Darwin embraced William Thomson´s idea of the earth being around 100 million years old, which seemed more suitable to hold the process of speciation than the 6000 years od theory.
