Explanation:

Gopal Baba Walangkar, also known as Gopal Krishna, (ca. 1840-1900) is an early example of an activist working to release the untouchable people of India. In 1888, Walangkar began publishing the monthly journal titled Vital-Vidhvansak (Destroyer of Brahmanical or Ceremonial Pollution), which was the first to have the untouchable people as its target audience. He also wrote articles for Marathi-language newspapers such as Sudharak and Deenbandhu, as well as composing couplets in Marathi that were intended to inspire the people.

Hence option 1st is correct.
