The correct answer is "Zwingli believed in the creation of a Christian state, while Calvin thought church and state should be separate".
Zwingli's position in regards to government's relation with the Church can be summarized in his idea of "divine sanction", which established a religious legitimization of the State's power. He believed that both the Church and the State represented God's way of guiding and ruling his followers.
On the other hand, Calvin put less emphasis on institutions as a representation of faith. He believed people had a predestined fate to either be saved or not, and that's how God's sovereignity worked on his people. Calvin thought that rulers could go against God's will and this would translate in the loss of their "divine right" to govern and should therefore be deposed.
Hope this helps!
