The correct option is D Guruji refused to convert and was executed in Delhi along with his companions.
Guru Tegh Bahadur was approached by a group of Kashmiri Pandits who were forced to convert to Islam by Mughal emperor Aurangzeb. His son, Guru Gobind Singh, advised Guruji to intervene personally to help the Kashmiri Pandits. Guruji handed the Guru Gaddi to his son before he made the journey to meet the emperor. On their trip to Delhi, Guruji and his companions were arrested in the Malikpur village. They were presented to the emperor and were given an ultimatum. They were given the choice to either convert to Islam or face execution. Being a staunch disciple of Sikhism, Guruji refused to convert. He and his companions attained matrydom and faced execution for defending the Sikh faith.
