The mandate heaven was affected by
a. the years of experience a dynasty had ruling others
b. the spiritual faith of the people under the rule of the dynasty
c. the gods and the way in which an emperor ruled
d. a person's social status at the time of birth

B , Without the faith if people there wouldnt have been a mandate of heaven it wouldve been just some random chinese dude saying he had the right to rule so the more people took the principle seriously the more power it had to influence , and thats how we ended up with the mandate

It is the Prophase as the first stage of four.
