I got this answer by the process of elimination. Not A - Because it is a holy book consisting of the words of God (or Allah) that were revealed to Muhammad in a cave. Not B- The Quran is known for being written in only one language--that's Arabic (translations may be done in different languages, but a Quran itself will always be in the Arabic language.)
