The popular leader known for leading the Bardoli satyagraha is Sardar Vallabhbhai Patel. The Bardoli satyagraha was a nonviolent protest movement carried out by the farmers of Bardoli taluka in Gujarat, India, during the British colonial rule. The movement aimed to oppose an unjust tax imposed by the British government on the farmers` land.

Option 1, Acharya J.B. Kriplani, was a prominent Indian independence activist and a member of the Indian National Congress, but he is not specifically associated with leading the Bardoli satyagraha.

Option 2, Lala Lajpat Rai, was also an important figure in the Indian independence movement, but he is not known for leading the Bardoli satyagraha.

Option 4, Pandit Jawaharlal Nehru, was the first Prime Minister of India and a key leader in the Indian independence movement, but he was not directly involved in leading the Bardoli satyagraha.

Therefore, the correct answer is option 3, Sardar Vallabhbhai Patel, who is well-known for his leadership in organizing and leading the Bardoli satyagraha.
