Choose the odd one out :

RBI

The correct answer is option (3) : RBI

1. NCERT ; National Council of Educational Research and Training, responsible for school education and academic research.

2. UGC : University Grants Commission, responsible for coordinating and maintaining the standards of university education.

3. RBI : Reserve Bank of India, the country's central banking institution, responsible for monetary policy and regulations of financial systems.

4. AICTE : All India Council for Technical Education, responsible for the development of technical education.

The odd one out here is RBI because it is primarily a financial institution related to monetary policy, while the others are involved in education sector.
