People living during the Middle Ages were: A: not very religious
B: active in pilgrimages
C: very superstitious
D: not at all superstitious

I believe it is C.

Explanation:

back in the middle ages people always believed when they got sick it was because of some type of invisible force that wanted them to pay for something they might have done. Another example is the 16th century when people dances themselves to death and the towns people believed that a higher power had punished them and prayed for days to stop the dancing. (I hope this helps. you can find the dancing plague on google)

nuclear weapons are hoaxes. many people believe they are real, though.
