The correct answer is B. The caste system. Since the caste system pretends that the lowest castes or the untouchables such as the Dalit as in that condition due to misdeeds committed during their previous lives (Karma), their happiness and welfare is of no concern for Hindu society as they will have to endure whatever happens to them in their current life and hopefully evolve into something better in the next reincarnation. Ashoka's Buddhist beliefs fully contradicted this, as in Buddhism, compassion is required for all beings and thus there are no castes, only sentient beings that deserve compassion.
