Explanation:

FICCI (Federation of Indian Chambers of Commerce and Industry) is not a regulatory body but rather an industry association that represents the interests of businesses in India. On the other hand, RBI (Reserve Bank of India), SEBI (Securities and Exchange Board of India), IRDAI (Insurance Regulatory and Development Authority of India), and PFRDA (Pension Fund Regulatory and Development Authority) are regulatory bodies responsible for regulating and supervising various segments of the Indian financial system, including banking, securities markets, insurance, and pension funds.
