The correct option is D Bhindranwale
The leader of the Sikh militant group, Bhindranwale, advocated the formation of a separate Sikh state called the ‘Khalistan’. The militants imposed strict orthodox life code on all Sikhs and non-Sikhs of Punjab. Non-Sikhs were attacked, and the movement turned into communal violence. These militants occupied Sikh holy shrine, the Golden Temple in Amritsar.
