The Dinesh Goswami Committee was primarily concerned with Option 2: electoral reforms. The committee was formed in 1990 by the Indian government to examine and suggest measures for electoral reforms in the country.

One of the main objectives of the Dinesh Goswami Committee was to address issues related to electoral processes and make recommendations to improve the functioning of democracy in India. The committee studied various aspects of the electoral system, including the role of political parties, funding of elections, criminalization of politics, and the use of money and muscle power during elections.

Electoral reforms were crucial at that time as there were growing concerns about the influence of money, corruption, criminal elements, and the erosion of democratic values in the electoral process. The committee aimed to identify these issues and propose effective solutions to strengthen the democratic fabric of India.

The committee recommended several important reforms, including the introduction of state funding of elections, stricter disclosure requirements for candidates and parties, implementation of a code of conduct for political parties, and measures to address criminalization in politics. These recommendations were aimed at promoting transparency, accountability, and fairness in the electoral process.

While the Dinesh Goswami Committee focused on electoral reforms, it`s worth noting that the other options mentioned in the question were not the primary concerns of this committee:

Option 1: De-nationalisation of banks - This issue falls within the domain of economic policy and was not a focus of the Dinesh Goswami Committee. The committee`s mandate was specifically related to electoral reforms and strengthening democratic processes.

Option 3: Steps to put down insurgency in the North-East - The committee`s scope did not extend to addressing issues of insurgency or security matters. Its primary objective was to address electoral reforms and the functioning of democratic institutions.

Option 4: The problem of the Chakmas - The Chakmas are an ethnic group in India, particularly in the state of Arunachal Pradesh. However, the Dinesh Goswami Committee`s mandate did not include addressing specific ethnic or community-related issues. Its focus was solely on electoral reforms.

In conclusion, the Dinesh Goswami Committee was primarily concerned with electoral reforms in India. It aimed to identify and address issues related to the electoral process, such as political party funding, criminalization of politics, and transparency. The committee`s recommendations played a significant role in shaping subsequent electoral reforms in the country.
