Answer: C. The first three books of the Qur’an
Explanation: The Christian Bible consists primarily of the New Testament, but also of the Old Testament, which is the Jewish Bible. Christians do not reject the Old Testament, which contains, among other things, Moses' five books - Torah, as well as other Jewish books that are not contained in Torah. The Christian New Testament, which represents the fulfillment of the Old Testament, together make up the Christian Bible.
What is not part of the Christian Bible, although one can argue about similarity, is the Qur'an as such and the first three books of this Holy Book of Islam.
