Mahatma Gandhi launched the 'Kheda Satyagraha' on which of the following issue?

For the remission of taxes following the failure of their harvest.

The correct answer is Option (3) → For the remission of taxes following the failure of their harvest.

Mahatma Gandhi was to spend much of 1917 in Champaran, seeking to obtain for the peasants security of tenure as well as the freedom to cultivate the crops of their choice. The following year, 1918, Gandhiji was involved in two campaigns in his home state of Gujarat. First, he intervened in a labour dispute in Ahmedabad, demanding better working conditions for the textile mill workers. Then he joined peasants in Kheda in asking the state for the remission of taxes following the failure of their harvest. These initiatives in Champaran, Ahmedabad and Kheda marked Gandhiji out as a nationalist with a deep sympathy for the poor.
