Correct answer: A. Shift from military conquest to moral conquest through Dhamma
Explanation: The direct answer is A: Ashoka shifted from military conquest toward moral conquest through Dhamma. Before the Kalinga War, the Mauryan state used armies to expand its territory. The war caused great death, suffering and displacement. Ashoka expressed remorse in his inscriptions and began giving greater importance to Dhamma, which included compassion, non-violence, respect for parents and teachers, fair treatment, and tolerance among religious groups. This did not mean that he suddenly abandoned administration or all defence; it means that peaceful moral influence became the main ideal of his policy. Option A is correct because it describes this change from victory by force to victory through ethical conduct. Option B is wrong because the Delhi Sultanate began centuries later and was not founded by Ashoka. Option C is wrong because Maratha Swaraj belongs to the much later seventeenth-century history of Shivaji. Option D is wrong because it does not identify the special post-Kalinga change in Ashoka’s policy; it is not the accepted description of his Dhamma policy. Memory cue: Kalinga caused remorse, and remorse led to Dhamma.
