Centre-State Relations Committees:

1. Sarkaria Commission
2. L M Singhvi Committee
3. Rajamannar Committee
4. M M Punchhi Commission

Explanation:

The Centre-State Relations in India have undergone several changes since independence. The Constitution of India has provided for the distribution of legislative and executive powers between the Union and the States. However, there have been several issues and conflicts between the Centre and the States regarding the distribution of powers, control over resources, and financial autonomy.

To address these issues, the Government of India has constituted several committees and commissions to examine the Centre-State Relations. The important committees are:

1. Sarkaria Commission: It was constituted in 1983 to examine the Centre-State Relations and suggest measures to strengthen them. The Commission submitted its report in 1988, which provided recommendations on various issues, such as the role of Governor, the appointment of Chief Ministers, the use of Article 356, and the sharing of resources.

2. L M Singhvi Committee: It was constituted in 1986 to review the working of the Constitution and suggest amendments to strengthen the Centre-State Relations. The Committee submitted its report in 1988, which provided recommendations on various issues, such as the role of Governors, the appointment of Chief Ministers, and the use of Article 356.

3. Rajamannar Committee: It was constituted in 1997 to examine the Centre-State Relations in the context of the emerging challenges of globalization, liberalization, and decentralization. The Committee submitted its report in 1998, which recommended measures to enhance the autonomy of the States and promote cooperative federalism.

4. M M Punchhi Commission: It was constituted in 2007 to examine the Centre-State Relations in the context of the changing socio-economic and political scenario. The Commission submitted its report in 2010, which provided recommendations on various issues, such as the role of Governors, the sharing of resources, the use of Article 356, and the promotion of cooperative federalism.

Therefore, the correct answer is option 'B' - 1, 3, 4, as the Sarkaria Commission, Rajamannar Committee, and M M Punchhi Commission all examined the Centre-State Relations.

Committees associated with centre state relations are:
Raj mannar committee, West Bengal memorandum, sarkaria commission, punchi commission, Anandpur sahib resolution etc.
