If I'm remembering correctly, the Protestant Reformation was a direct challenge to the Catholic church during the Renaissance. The Renaissance spirit of questioning authority (A) WAS a cause. During this time period, the Renaissance, people were beginning to think for themselves about the traditions they had followed for centuries--including the Catholic church.
The sale of indulgences (B) was also a cause: people were unhappy that the Catholic church was making money by selling forgiveness of your sins. That's just not right! It drove many people away from Catholicism.
