The correct answer is English. Bal Gangadhar Tilak, born Keshav Gangadhar Tilak, was an Indian nationalist, teacher, enhanced independence activist. He was one-third of the Lal Bal Pal triumvirate. Tilak was the first leader of the Indian independence movement. Bal Gangadhar Tilak used to run his two newspapers, Kesari, in Marathi and Mahratta in English from Kesari Wada, Narayan Peth, Pune. The newspapers were originally started as a co-operative by Chiplunkar, Agarkar, and Tilak. The newspaper was used as a spokes piece for the Indian national freedom movement and continues to be published. The Mahratta, the weekly English newspaper saw the light of the day on the 2nd of January 1881. It is considered to be the senior to the Kesari by two days. Hence, the correct answer is 'English'. Additional InformationThe editors of Kesari included a number of freedom fighters and social activists/reformers, including Agarkar, Chiplunkar, and Tilak. Agarkar left Kesari in 1887 to start his own newspaper, Sudharak (The Reformer) after which Tilak continued to run the paper on his own. Narasimha Chintaman Kelkar, a close associate of Tilak, served as editor twice when Tilak was imprisoned in 1897 and 1908. The Wada was originally known as Gaikwadwada and owned by Sayajirao Gaikwad III the Maharaja of the Princely state of Baroda. It was sold to Tilak by the Maharaja in 1905 at a fair price. The original Wada where Tilak published the newspaper still houses the current day offices of Kesari.
