Concept:Ad-Dhikr is another title for the Qur'an, and Ummul-Kitab is another title for a specific chapter of the Qur'an.
Explanation:In Islamic terminology, the Qur'an is widely known as Ad-Dhikr, meaning "the Reminder."
Similarly, Ummul-Kitab means "Mother of the Book."
This title is given to Surah Al-Fatihah because it summarizes the core message of the Qur'an.
The analogy compares the name of the whole book to the name of a chapter.
Thus, just as Ad-Dhikr identifies the Qur'an, Ummul-Kitab identifies Surah Al-Fatihah.
Answer:Therefore, the correct option is B. Fatihah.
