The use of local languages in medieval literature was most revolutionary because

a.) it reached a wider audience of people
b.) it led to italian becoming the primary language in europe
c.) it was recognized by the church as the best way to reach the masses
d.) it led to a mass increase in university enrollments

The correct answer is A)

The use of local languages in medieval literature was most revolutionary because it reached a wider audience of people.                                                                              

For example, in 1260, Brunetto was exiled in France, where he composed the Tresor in French in order to reach a wider public. This vast encyclopedia is formed of three books, covering a variety of disciplines including theology, physics, astronomy and ethics.

Brunetto’s Tresor was extremely successful, and copies circulated widely across the Mediterranean. By the 14th century, it was translated into other vernaculars, notably Catalan and Castilian.
