Small Industries Development Bank of India (SIDBI) is not a subsidiary of the Reserve Bank of India (RBI). It was established as an independent financial institution to support small and medium-sized enterprises (SMEs) in India.
The other options are or were subsidiaries of RBI:
- National Housing Bank (NHB) was a subsidiary but is now under the Government of India.
- NABARD was initially promoted by RBI but now operates independently.
- Bharatiya Reserve Bank Note Mudran Private Limited (BRBNMPL) is a fully-owned subsidiary of RBI responsible for printing currency notes.
Thus, the correct answer is SIDBI.
