The correct option is B Qazi Rukun-ud-Din
At Mecca, Guru Nanak slept with his feet towards the Kaba. He was objected by Qazi Rukun-ud-Din, who was the shrine caretaker at Mecca. When he tried to rotate his feet away from the Kaba, all of Kaba moved to remain in the direction of Guru Nanak's feet. Seeing this, he became astonished and became his disciple.
