The correct answer is: D. 1672 AD
The Satnamis revolt was a major uprising against the Mughal Empire in 1672 AD. It was led by Guru Ghasidas, a religious leader who preached against the caste system and the oppression of the poor. The revolt was initially successful, but it was eventually suppressed by the Mughals.
The Satnamis were a group of people who were originally from the Chhattisgarh region of India. They were followers of Guru Ghasidas, who preached a message of equality and social justice. The Satnamis were opposed to the caste system, and they believed that all people were equal in the eyes of God.
The Satnami revolt began in 1672 AD, when Guru Ghasidas led a group of his followers in an attack on a Mughal fort. The revolt was initially successful, and the Satnamis were able to capture several forts. However, the Mughals eventually suppressed the revolt, and Guru Ghasidas was killed.
The Satnami revolt was a significant event in Indian history. It was one of the first major uprisings against the Mughal Empire, and it showed that the common people were willing to fight for their rights. The revolt also helped to spread the message of Guru Ghasidas, and it led to the establishment of the Satnami sect.
The other options are incorrect because they are not the years in which the Satnamis revolt took place.
