The answer is C and D: God, or the One, is the perfect source of Goodness from which all other things come; God is so utterly perfect that humans can never hope to share in God's eternal Goodness.
Neoplatonism, a form of philosophy born around the 3rd century C.E. is a form and extension of platonic thought that —even though, because of the complexities of those who we now call Neoplatonist philosophers, is impossible to encapsulate in a single form of thought— formulated, in general terms, the meaning of God as the One —or Idea, in Plato— from which all goodness derives or emanates and in which, in the scale of Being, humans are but a stepping transition (immersed in multiplicity) in the hierarchy of Goodness, Completion or absolute Being.
