The correct option is B By encouraging women to both sit and serve in Pangat.
Sati was a practice where a woman would fling herself on her husband’s funeral pyre. Guru Amardas Ji criticised this practice and preached against it. Guruji also discouraged the Purdah system in which women were to stay behind the ‘Purdah’ or curtain, unseen. Guruji believed that this practice hindered the development of a woman. Thus, he asked women to both sit and serve in Pangat.
