The correct answer is option 3, Shivaji. Shivaji was a Maratha warrior king who is credited with pioneering the guerrilla warfare methods in India. Guerrilla warfare is a type of warfare in which small, mobile groups of fighters use tactics such as ambushes, hit-and-run attacks, and irregular warfare to harass and disrupt larger, more conventional armies. Shivaji and his Maratha forces used these tactics effectively against the more powerful Mughal empire, which allowed them to challenge and sometimes defeat much larger armies. Shivaji`s guerrilla warfare methods were based on strategic planning, knowledge of the terrain, and quick mobility, which gave them a significant advantage over their opponents. This innovative approach to warfare was a key factor in Shivaji`s success and his legacy as a military leader.
