Explanation:

- Option 1: RBI (Reserve Bank of India) focuses on monetary policy, financial regulation, and economic research but does not prepare the Economic Survey.

- Option 2: Ministry of Finance is responsible for preparing the Economic Survey. This document is usually presented a day before the Union Budget and reviews the country's economic development and policy initiatives.

- Option 3: SEBI (Securities and Exchange Board of India) regulates the securities market and protects investor interests.

- Option 4: IRDA (Insurance Regulatory and Development Authority) regulates the insurance industry.

- Option 5: (1) and (2) combined is incorrect as RBI is not involved in this document's preparation.
