   D. "Know thyself"

Explanation:  The Temple of Apollo in Delphi, in ancient Greece, was a sanctuary where destiny was foretold to people, hence the place of the holy oracle. When people were in a crucial situation, they would go to this temple to find out what to do next. The inscription that stood above the entrance signified the meaning and depth of the ancient religions, which can still be heard today through the various influences of these religions. Knowing yourself means to dive into the depths of our own selves, to understand who we are and what we are, and in this way we reach the divine, after which further paths in life are opened.
