These changes impacted the way we teach and see history for years to come. In events such as the Murder of Nanking (committed by Japan), the horrors committed in the Polish termination camp (Auschwitz), and the Holocaust Twin experiment, many people were murdered and faced many cruelties. Now we study the works of Hitler, Stalin, and many others like them with caution. Though some people still believe that what Hitler did was correct (neo-nazis) or that the entire holocaust was completely made up (this is a false statement), it was a real event and had cause many people pain, and lots of people lost loved ones.
The answer is B purely due to this statement: "secures the blessings of liberty" which is in the preamble. Also because it is defined as a natural right. Hope this helps and let me know if you need more help!
