1. The journal 'Vital-Vidhvansak' (meaning Destroyer of Brahmanical or Ceremonial Pollution) is considered the first monthly journal specifically aimed at the untouchable people as its target audience. 2. It was published by Gopal Baba Walangkar (also known as Gopal Krishna) starting in 1888. 3. Walangkar was a significant early social reformer from the Mahar community in Maharashtra, preceding Dr. Ambedkar, and was influenced by Jyotiba Phule. 4. Jyotiba Phule (B) was a major social reformer but did not publish this specific journal. 5. Mohandas Karamchand Gandhi (C) and Bhimrao Ramji Ambedkar (D) were prominent leaders who worked extensively for the upliftment of untouchables later, and they had their own publications (e.g., Harijan by Gandhi, Mooknayak by Ambedkar), but they did not publish Vital-Vidhvansak. 6. Therefore, the correct answer is Gopal Baba Walangkar.
