The answer which was not a cause of the European Enlightenment is the monastic movement. Enlightenment has to do with renewal of humanistic sciences, where the center of the world is the man, and not church or religion. The other options all have to do with some kind of reformation or revolution, whereas the monastic movement has to do with changes within the church, which, as I said, wasn't as relevant in the era of Enlightenment. This era valued innovation, technology, the man and his relations with the environment, secularism (as opposed to religion), and not God and his behavior towards humankind.
