Correct option is B
The first exclusively Hindi-language newspaper was 'Udant Martand', which was launched on May 30, 1826. Contrary to the mention of Kanpur in the question, the newspaper was actually published from Kolkata (Calcutta), not Kanpur. Its editor and founder was Pandit Jugal Kishore Shukla. Despite the significance of being the first Hindi-language newspaper, 'Udant Martand' struggled due to financial issues and low readership, and it ceased publication after about a year.
