The correct answer is: A) Land reforms.
Karshaka Sanghams (peasant organizations) were instrumental in mobilizing for land reforms. They fought for the rights of peasants to own land and to have a fair share of the profits from their labor. They also fought against the exploitation of peasants by landlords and moneylenders.
Educational rights are the rights of all people to have access to education, regardless of their race, religion, gender, or social class. Temple entry is the right of all people to enter temples, regardless of their caste or religion. Abolition of untouchability is the practice of treating people of certain castes as untouchables.
All of these are important issues, but land reforms were the primary focus of the Karshaka Sanghams.
