The Sarkaria Commission made recommendations regarding the following:

The correct answer is (b), Union-State relations.

The Sarkaria Commission was a commission set up by the Government of India in 1983 to review the working of the Constitution of India with respect to Centre-State relations. The Commission submitted its report in 1988.

The Commission made a number of recommendations, including the following:

• The Centre and the States should have a more cooperative relationship.
• The Centre should not interfere in the affairs of the States.
• The States should have more autonomy.
• The Finance Commission should be given more powers.
• The Inter-State Council should be made more effective.

The Commission’s recommendations were not implemented in full, but they did have some impact on the way in which Centre-State relations are conducted.

• (a) Administrative reforms: The Sarkaria Commission did not make any recommendations regarding administrative reforms.
• (c) Panchayats: The Sarkaria Commission did not make any recommendations regarding panchayats.
• (d) Urban Governance: The Sarkaria Commission did not make any recommendations regarding urban governance.
