The correct answer is: A. Lala Duni Chand
Lala Duni Chand was a prominent Indian politician and freedom fighter. He was a member of the Indian National Congress (INC) and served as the Chief Minister of Himachal Pradesh from 1963 to 1967.
In 1965, an investigation committee was organised by the INC, under the Chairmanship of Lala Duni Chand, to investigate the Dhami Firing Tragedy. The committee found that the firing was unprovoked and that the police had used excessive force. The committee also found that the police had not followed the standard operating procedures for dealing with public protests.
The committee’s report was submitted to the government of Himachal Pradesh. The government accepted the report and took action against the police officers who were responsible for the firing. The government also announced compensation for the families of the victims.
The Dhami Firing Tragedy was a major event in the history of Himachal Pradesh. It led to a change in the way the police handled public protests. It also led to a greater awareness of the rights of the people.
The other options are incorrect because they are not the names of the people who were appointed to investigate the Dhami Firing Tragedy.
