Concept:In Islamic angelology, angels have distinct roles, and the guardian of Paradise is Riḍwān.
Explanation:Every angel in Islam has a specific responsibility given by Allah.
Mikail is in charge of providing food, rain, and general sustenance.
Israfil is the angel assigned to blow the trumpet announcing the Day of Resurrection.
Israil is not recognised as the angel who administers Paradise.
Riḍwān, on the other hand, is the guardian appointed to keep the gates of Jannah (Paradise).
He welcomes the believers and oversees the blessings of Paradise.
His name is given in the Prophetic narrations, although it does not occur explicitly in the Qur'an.
Thus, among the options listed, the angel in charge of paradise is Riḍwān.
Answer:B. Ridwan.
