Row 1 is Incorrect: The R.N. Malhotra Committee was constituted in 1993 by the Government of India, not the Insurance Regulatory and Development Authority of India (IRDAI). In fact, the IRDAI was established in 1999 as a direct result of this committee's recommendations to reform the insurance sector.

Row 2 is Correct: The L.C. Gupta Committee was appointed by the Securities and Exchange Board of India (SEBI) in 1996 to develop a regulatory framework and prepare a roadmap for the introduction of derivatives trading in India.

Row 3 is Incorrect: The Urjit R. Patel Committee was constituted in 2013 by the Reserve Bank of India (RBI) to revise and strengthen the Monetary Policy Framework, not for reforming bank lending to the housing sector. It famously recommended the adoption of flexible inflation targeting and the creation of the Monetary Policy Committee (MPC).

Row 4 is Correct: The Y.H. Malegam Committee was constituted in 2010 by the Reserve Bank of India (RBI) to study issues and recommend regulations for the Microfinance sector (NBFC-MFIs) following the Andhra Pradesh microfinance crisis.

Therefore, only rows 2 and 4 are correctly matched.
