The Sarabandi (no tax) campaign was an important part of the Indian freedom struggle that emphasized non-cooperation and peaceful revolt against the oppressive policies of British rule. The correct answer is Vallabhbhai Patel.

Option 1, Bhagat Singh, is not correct as Bhagat Singh was a revolutionary who believed in direct action and armed rebellion against the British, which is different from the peaceful non-cooperation of the Sarabandi campaign.

Option 2, Chittaranjan Das, was also a key figure in the Indian National Movement and established the Swaraj Party. However, he did not lead the Sarabandi (no tax) campaign.

Option 3, Rajaguru, was another revolutionary figure who, like Bhagat Singh, was involved in direct action against the British and was not associated with the Sarabandi campaign.

Option 4, Vallabhbhai Patel, is the correct answer. He played a significant role in organizing the peasants of Bardoli against the increase in land revenue by the British in 1928, leading what became known as the Bardoli Satyagraha. This campaign was effectively a tax revolt, where the peasants resolved not to pay revenue, known as a "Sarabandi"
