The correct answer is option 3: 1, 2 and 3.

Option 1 states that the uprisings refer to a series of skirmishes between the English East India Company and a group of sannyasis and fakirs. This is correct as the Sannyasi and Fakir uprisings were indeed conflicts between the English East India Company and these religious groups.

Option 2 states that one reason for the uprising was the ban on free movement of the sannyasis along pilgrimage routes. This is also correct as the restrictions on their movement was one of the main triggers for these uprisings.

Option 3 states that in the course of the uprisings, Warren Hastings issued a proclamation banishing all sannyasis from Bengal and Bihar. This information is correct as well, as Hastings did issue such a proclamation during the uprisings in 1773.

Option 4 is not correct as it states that the uprisings were contemporaneous with the Non-Cooperation Movement. However, the Sannyasi and Fakir uprisings took place in the late 18th century, while the Non-Cooperation Movement occurred in the early 20th century.

In conclusion, options 1, 2, and 3
