Answer:
A. Europeans were permanently divided into two religions, Catholicism and Protestantism.
Explanation:
The Reformation was the religious (and political) movement that caused the permanent religious division of Western Europe: Countries like Spain, Italy, France, Belgium, Austria, most of Switzerland, and Southern Germany, continued to be Catholic, while Scandinavia, Northern Germany, some areas of Switzerland, the Netherlands, and Great Britain, became Protestant.
Protestanism separated from the Catholic Church inspired by the thesis of Martin Luther, a German monk who denounced the corruption inside the Catholic world.
Some Protestant denominations are: Anglicanism in England, Calvinism in Switzerland, and Lutheranism in Northern Germany and Scandinavia.
