The results of Asoka’s transformation after the Battle of Kalinga include:
B. stone pillars telling of focus on people's well-being - Asoka erected stone pillars and edicts that promoted moral values and the welfare of his subjects.
C. Buddhism spreads - Asoka converted to Buddhism after the battle and promoted its teachings, leading to its spread both within his empire and beyond.
The other options (A, D, and E) do not reflect the outcomes of Asoka's transformation. After Kalinga, Asoka pursued policies of non-violence and sought to improve the welfare of his people, rather than increasing warfare or decreasing education. His transformation did not result in a loss of respect for ancestral heritage; rather, it reinterpreted it through the lens of Buddhist values.
