Correct Answer:
A. Hazrat Yaqoob (AS)
The correct answer is Hazrat Yaqoob (AS). 'Israel' is the revered title of Prophet Yaqoob (AS), meaning 'servant of God' or 'one who strives with God'. The descendants of Prophet Yaqoob (AS) are known as the Children of Israel (Bani Israel), a term frequently used in the Quran to refer to the Jewish people.
Hazrat Younus (AS) is known for his story with the whale.
Hazrat Ishaq (AS) was the son of Prophet Ibrahim (AS) and father of Prophet Yaqoob (AS).
Hazrat Yousaf (AS) was the son of Prophet Yaqoob (AS) and known for his beautiful story in the Quran.
Each prophet has distinct identities and titles, making Yaqoob (AS) the sole bearer of the title Israel.
