The correct option is C Sati
Sati was a custom or act of a Hindu widow burning herself to death on her husband’s funeral pyre. Reformers like Ishwarchandra Vidyasagar, Raja Rammohan Roy, Mahatma Jyotirao Phule, Savitribai Phule, Maharshee Dhondo Keshav Karve, Pandita Ramabai, and Ramabai Ranade took the initiative to end social evils like Sati and child marriage.
