The correct answer is: A. 15th January, 1948.
The Himalayas Prant Provisional Government was set up on 15th January, 1948 in the Garhwal region of Uttarakhand, India. It was a short-lived government that was formed by the Praja Mandal, a political party that was fighting for the independence of the Garhwal region from British rule. The government was led by Govind Ballabh Pant, who later became the Chief Minister of Uttar Pradesh. The Himalayas Prant Provisional Government was dissolved on 27th January, 1949, after the Indian government agreed to grant independence to the Garhwal region.
The Himalayas Prant Provisional Government was set up in response to the growing demand for independence in the Garhwal region. The Praja Mandal had been campaigning for independence for several years, and the government was seen as a way to achieve this goal. The government was also seen as a way to protect the interests of the Garhwal people, who felt that they were being neglected by the British government.
The Himalayas Prant Provisional Government was a short-lived government, but it played an important role in the history of the Garhwal region. It was the first government to be formed in the region, and it helped to raise awareness of the issue of independence. The government also helped to unite the people of the Garhwal region, and it laid the foundation for the future independence of the region.
The other options are incorrect because they are not the dates on which the Himalayas Prant Provisional Government was set up.
