Although the question has no options, we can comment on the following.
One significant continuity in the power of the European monarchs during the period 1450-1598 were the monarchies of King Charles V of England and Queen Elizabeth I of England.
King Charles V reign started in 1519 and ended in 1556). Queen Elizabeth I reigns started in 1558 and ended in 1603. Those years were dominated by the centralization of power that made the European kings be absolutists rulers that granted no rights to their subjects. They imposed heavy taxation of farmers and merchants but gave privileges to the Noble people to maintain a "healthy" relationship with them.
