Explanation

The second month of the Islamic calendar is Safar. However, based on common knowledge and typical curriculum emphasis, Rajab (the third month) or a specific sequence might be expected; assuming standard order, Safar is indeed the second month. Option B, Rajab, is the third month. Option C, Rabi-ul-Awwal, is the ninth month. Option D, Rabi-us-Sani, is not a recognized primary month name in the standard Islamic calendar sequence.
