The correct answer is Lokmanya Tilak.
Bal Gangadhar Tilak, popularly known as Lokmanya Tilak, gave this famous slogan during the Indian freedom struggle. He was one of the earliest and most influential leaders to demand complete self rule from British India.
Tilak used this line to inspire ordinary people to actively demand independence rather than wait for gradual reforms. He is remembered as one of the founding figures of assertive nationalism in India.
