Step-by-step explanation:
Lutheranism gained relatively quick success in Germany and Scandinavia due to several factors. Firstly, Martin Luther's teachings resonated with many people who were critical of the practices of the Catholic Church.
Luther emphasized the importance of faith alone for salvation, which appealed to those who were seeking a more personal and direct relationship with God.

Some princes saw Lutheranism as an opportunity to gain more control over their territories and to challenge the authority of the Catholic Church. Others may have been influenced by political motivations or personal convictions. Option A) is the correct one.
