The correct answer is D. no article.
The Quran is the holy book of Islam, and it is believed to be the direct word of God as revealed to the prophet Muhammad. It is a collection of 114 chapters, or suras, which are divided into verses, or ayat. The Quran is the most important source of Islamic law and theology, and it is recited daily by Muslims around the world.
The Quran is not preceded by an article because it is considered to be a unique and sacred text. It is not simply a book, but rather the word of God. As such, it is not necessary to use an article before it.
The other options are incorrect because they all imply that the Quran is just one of many books. This is not the case, as the Quran is considered to be the supreme authority in Islam.
