The statement that best explains the Catholic Church's response to the Protestant Reformation is:
The Church reaffirmed core Catholic teachings such as the Eucharist and the supremacy of the Church in interpreting the Bible.
This response aligns with the key elements of the Tridentine Creed that emphasize the importance of traditional doctrines and the authority of the Catholic Church, particularly in areas like the interpretation of Scripture and the significance of the sacraments, which were central points of contention during the Reformation.
