The correct option is C musalman
The hymn from Asa Di Var uses the word 'musalman' in it. Aurangzeb asked Baba Ram Rai, son of Guru Har Rai Ji to clarify its meaning. However, Ram Rai did not want to displease the emperor. He cleverly clarified to Aurangzeb that the word 'Musalman' was wrongly written for 'beiman', which means, a dishonest person. Aurangzeb was satisfied with this answer.
