Explanation

Gopal Baba Walangkar (also known as Gopalnak Vithalnak Walangkar) was a pioneer of the Dalit emancipation movement in Maharashtra:

– In 1888, he launched the historic monthly journal Vital-Vidhvansak (‘Destroyer of Ceremonial/Brahmanical Pollution’), recognized as the first journal directed specifically at articulating the grievances and rights of the untouchable communities.
– In 1889, he also authored *Vital Vidhvansan*, challenging religious justifications for untouchability and advocating for social equality and civic recruitment of depressed classes into the British military.

Therefore, the journal was published by Gopal Baba Walangkar — Option A.
