Step 1: Understanding Satya and Dharma.
M.K. Gandhi considered "Satya" (truth) the heart of "Dharma" (righteousness). This concept was central to his philosophy of non-violence and truth. He viewed truth as both a moral imperative and a path to God.
Step 2: Option Analysis.
- (1) Raja Rammohan Roy: Roy's focus was primarily on rationalism and modernity, not Gandhi's specific connection between truth and righteousness.
- (2) V.D. Savarkar: Savarkar championed Hindutva, a political philosophy distinct from Gandhi’s focus on truth and non-violence.
- (3) M.K. Gandhi: Gandhi saw Satya as the foundation of Dharma, emphasizing truth and non-violence as guiding principles.
- (4) B.R. Ambedkar: Ambedkar prioritized social justice and the rights of marginalized groups; Satya was not as central to his philosophy as it was to Gandhi's.
Step 3: Conclusion.
The correct choice is (3) M.K. Gandhi.
