Concept:
- NITI Aayog was set up in January 2015 by the Government of India, replacing the earlier Planning Commission.
- NITI stands for National Institution for Transforming India.
- It works as a policy think tank that gives strategic and technical advice to the central and state governments, rather than directly allocating funds like the old Planning Commission did.
Step 1: Recall what NITI Aayog is.
It is the body that replaced the Planning Commission in 2015 as the government's main policy think tank.
Step 2: Expand the acronym correctly, word by word.
N stands for National, I stands for Institution, T stands for Transforming, I stands for India, giving National Institution for Transforming India.
Step 3: Compare against the close-sounding wrong options.
'Nation Institute', 'New Institute', and 'Nodal Institute' are all near-miss wordings that do not match the actual, officially used expansion.
Final Answer: National Institution for Transforming India
