Step 1: NITI Aayog's Role:
The National Institution for Transforming India (NITI Aayog) is the Indian government's primary policy think tank, providing policy and strategic direction.
Step 2: Identifying the Predecessor:
NITI Aayog was established on January 1, 2015, by the NDA government, replacing the Planning Commission. The shift aimed to transition from centralized planning to cooperative federalism, involving states as development partners.
Step 3: Examining Other Options:
Finance Commission: This constitutional body (Article 280) defines financial relations between the central and state governments, operating independently and established every five years.
Commerce and Industry Commission and Labour Commission: These are not permanent bodies like the Planning or Finance Commissions, often created for specific tasks and durations.
Step 4: Conclusion:
The Planning Commission was replaced by NITI Aayog.
