The major demand of the Bardoli Satyagraha (1928), led by Sardar Vallabhbhai Patel, was the rollback of the newly enhanced revenue rate. This means that the farmers participating in the satyagraha protested against the increase in the land revenue rates imposed by the British government.

Option 1: Land to the Tiller - This option is not the major demand of the Bardoli Satyagraha. Land to the Tiller refers to the redistribution of land to the farmers who till it, which was not the specific focus of this satyagraha.

Option 2: Increase in the rates of labor wage - This option is also not the major demand of the Bardoli Satyagraha. The main focus of the satyagraha was on the issue of increased land revenue rates, rather than labor wages.

Option 4: Supply of agricultural inputs to the farmers at subsidized rate - This option is not the major demand of the Bardoli Satyagraha. While it is related to the farmers` concerns, it is not the central demand of this particular satyagraha.

In conclusion, option 3, the rollback of the newly enhanced revenue rate, accurately represents the major demand of the Bardoli Saty
