Explanation:

Jai Prakash Narayan (Correct): Jai Prakash Narayan (1902–1979), popularly known as JP, was an Indian independence activist and political leader. He propounded the concept of "Sampoorna Kranti" (Total Revolution) in 1974, calling for a comprehensive transformation of society across social, economic, political, and cultural aspects, particularly in response to the perceived corruption and authoritarianism of the Indira Gandhi government. Bal Gangadhar Tilak: He was an early leader of the Indian independence movement, known for "Swaraj is my birthright," but not for "Sampoorna Kranti." Ram Manohar Lohia: He was an Indian socialist political leader, advocating for a specific type of socialism, but the term "Sampoorna Kranti" is associated with JP. Lala Lajpat Rai: He was an Indian nationalist leader and part of the 'Lal-Bal-Pal' triumvirate, focused on national independence and social reform, not this specific concept.
