The correct option is B Vali Kandhari became his follower.
Guru Nanak Ji reached Hasan Abdal near Rawalpindi, where he encountered Vali Kandhari, an arrogant Muslim fakir. Vali Kandhari hurled a stone at Guruji in a fit of rage. According to the legends, Guruji stopped the stone with his hand and left Vali dumbfounded. Gurdwara Punja Sahib was built here to commemorate Guru Nanak’s visit to Hasan Abdal.
