Q.Which of the following is the apex institution for agricultural and rural credit in India?

Rural credit in India flows through several institutions, but only one of them was set up specifically as the apex, refinancing body for agriculture and rural development.

Why (b) is correct: NABARD, established in 1982, is the apex institution that refinances co-operative banks, Regional Rural Banks and commercial banks for agricultural and rural lending, coordinates rural-credit policy nationally, and promotes rural infrastructure and microfinance (including the SHG–Bank Linkage Programme). No other institution in the list plays this specific apex role for agriculture and rural credit.

Why the others are wrong:

• (a) The Reserve Bank of India is India's central bank, responsible for monetary policy and overall banking-sector regulation — it oversees the banking system broadly but is not the specialised apex body for agricultural/rural credit; that role was carved out for NABARD.
• (c) SEBI regulates India's securities and capital markets (stock exchanges, listed companies, mutual funds) and has no role in agricultural credit.
• (d) SIDBI is the apex institution for financing and promoting small-scale industry, not agriculture or rural credit specifically.

NABARD is sometimes confused with the RBI because both are described as apex/central institutions — the distinguishing point is NABARD's specific mandate for agriculture and rural development, while the RBI's mandate is the entire banking and monetary system.
