The `Dhamma` propagated by Ashoka refers to his system of morals that were consistent with the teachings of most of the sects during that time. Option 1, which states that the `Dhamma` was the tenets of Buddhism, is incorrect. While Ashoka played a major role in the spread of Buddhism and promoted its teachings, the `Dhamma` he propagated was not limited to Buddhism alone.
