Explanation
The slogan "Swaraj is our birthright" was coined by Bal Gangadhar Tilak, therefore the correct answer is C: Bal Gangadhar Tilak.
Bal Gangadhar Tilak was an Indian nationalist, social reformer, and freedom fighter who played a key role in India's struggle for independence from British colonial rule. He was one of the earliest advocates of Swaraj (self-rule) and believed that India should be governed by Indians themselves.
The slogan "Swaraj is our birthright" was first used by Bal Gangadhar Tilak at the Indian National Congress session in Calcutta (now Kolkata) in 1906. The slogan became very popular among Indians who were fighting for independence and it soon became a rallying cry for the Indian freedom movement.
Tilak believed that political freedom was essential for India's progress and he worked tirelessly to mobilize the masses and create awareness about the need for Swaraj. His efforts inspired many other freedom fighters, including Mahatma Gandhi, who later became the leader of the Indian independence movement.
