Answer:
B. he rededicated the shrine to monotheism and Allah
Step-by-step explanation:
the Abrahamic religions believe that the Black Stone of the Kaaba was given to Abraham by the spirit Gabriel and had since then been the symbol of their faith.
when Muhammad conquered Mecca, the shrine was reportedly used to house idols of pagan Gods. Muhammad had the shrine cleaned of all idols and rededicated the black stone to Allah, reinstating monotheism and making a center of worship for the newly formed Islam.
