b. reject humanism movement and classic greek works

c. establish a middle ground between catholics and protestants

d. conceal corruption in the catholic and protestant churches

The correct answer is C.

Desiderius Erasmus (1466-1536), also known as Erasmus of Rotterdam, was a Dutch Christian humanist, contemporaneous of Luther's Reform but who never got involved on it. He remained faithful to traditional faith and to the Roman Catholic Church, not sharing Luther's principle of faith alone, but he coincided with him in condemning the corruption and abuses existent within the Catholic church institution.

Erasmus called for some religious reform, and in this line he established an intermediate stage, called middle road (or "Via Media") between the Catholic doctrine and Luther's reform.
