Correct Answer:
B. حضرت زینب بنت جحشؓ
The question pertains to the marriage of Prophet Muhammad (PBUH) in the fifth year of Hijra. The Prophet (PBUH) married Hazrat Zainab bint Jahsh (R.A.) in the 5th year of Hijra. This marriage was divinely ordained and addressed a significant social custom of the time regarding adopted sons, as Zainab (R.A.) was previously married to Zayd ibn Harithah, the Prophet's adopted son.
- Option B (حضرت زینب بنت جحشؓ) is correct as her marriage to the Prophet (PBUH) took place in the 5th year of Hijra.
- Options A (حضرت صفیہؓ), C (حضرت جویریہؓ), and D (حضرت ام سلمہؓ) were also Mothers of the Believers, but their marriages to the Prophet (PBUH) occurred in different years. Hazrat Umm Salamah (R.A.) was married in the 4th year of Hijra, while Hazrat Safiyyah (R.A.) and Hazrat Juwayriyah (R.A.) were married later.
