Although the question does not provide options or any other reference, we can say the following.
The cosmological argument relies on what many (but not all) philosophers accept as a basic metaphysical principle that accepts the principle of one great creator of the universe. Many times called god, this "unknown entity" is the one that set things in motion in the cosmos. This particular or magical entity, under the natural theology vision, is the force behind everything in the universe, and this tries to confirm the existence of one creator god.
