Final answer:
The longest Surah in the Quran is b) Surah Al-Baqarah, which is the second chapter and contains 286 verses.
Step-by-step explanation:
The longest Surah in the Quran is b) Surah Al-Baqarah. The Quran consists of 114 chapters, which are known as Surahs. Each Surah has a unique name, often derived from a significant event, theme, or topic. Surah Al-Baqarah is the second chapter of the Quran but is the lengthiest, containing a total of 286 verses. The Quran is organized with the chapters arranged approximately from the longest to the shortest. Therefore, the sequence begins with Surah Al-Fatiha, and Surah Al-Baqarah follows as the next chapter, being the longest. It is worth noting that the importance of a Surah is not tied to its length but rather its content and the message it conveys to the believers.
