The Champaran Satyagraha of 1917 is a prime example of a:

Peasant movement
Tribal rebellion
Labor strike
Nationalist protest.

The Champaran Satyagraha of 1917 was a peasant movement led by Mahatma Gandhi in the Champaran district of Bihar, India. The movement was against the British government’s indigo plantation system, which forced peasants to grow indigo on their land for little or no pay. The satyagraha was successful in getting the British government to abolish the indigo plantation system.

A peasant movement is a social movement that aims to improve the lives of peasants. Peasants are farmers who own or work small farms. They are often poor and exploited by landlords, moneylenders, and other powerful groups. Peasant movements have been a major force for social change in many parts of the world.

A tribal rebellion is a revolt by a tribal group against the government or another powerful group. Tribal groups are often indigenous peoples who live in remote areas. They may have their own unique culture and way of life. Tribal rebellions are often caused by government policies that threaten tribal land, resources, or culture.

A labor strike is a work stoppage by employees in order to pressure their employer to meet their demands. Labor strikes are a common form of protest in many countries. They can be effective in winning higher wages, better working conditions, and other benefits for workers.

A nationalist protest is a protest against the government or another powerful group that is seen as being oppressive or unjust. Nationalist protests are often motivated by a desire for national independence or self-determination. They can be peaceful or violent.

In the case of the Champaran Satyagraha, the correct answer is peasant movement. The movement was led by Mahatma Gandhi, who was a lawyer and activist who believed in non-violent resistance. The movement was successful in getting the British government to abolish the indigo plantation system.
