Option d is the correct answer. The Mimamsa system of philosophy, also known as Purva Mimamsa or Karma Mimamsa, is one of the six orthodox schools of Hindu philosophy that focuses on the interpretation and application of the Vedas, the sacred scriptures of Hinduism. The word Mimamsa means "investigation" or "inquiry" in Sanskrit. The Mimamsa school holds that the performance (Karma) of rituals and moral duties prescribed by the Vedas is the primary means of attaining liberation (moksha), which is the ultimate goal of human life. The school does not emphasize the concepts of knowledge (gyan), devotion (bhakti), or meditation (yoga) as the paths to liberation, unlike some other schools of Hindu philosophy .
