When a new family takes control, then a new dynasty begins. The Mandate of Heaven is what the Chinese people believed gave their rulers the right to be king or emperor. It meant that the gods had blessed that person with the right to rule. A ruler had to be a good and just ruler to keep the Mandate of Heaven.
A seems the most logical in this sense, since parents are portrayed (and majority do) sacrifice a lot so their children can live good and better lives than they did.
