Sh. P.V. Narasimha Rao is often referred to as the "Father of Indian Economic Reforms" for his critical role as Prime Minister in initiating the liberalization of India’s economy in 1991. Facing a severe balance-of-payments crisis, Rao provided the political leadership to implement transformative reforms, including reducing trade barriers, deregulating industries, and encouraging foreign investment. While Dr. Manmohan Singh, as Finance Minister, was the chief architect of these reforms, designing and executing the economic policies, Rao’s vision and approval were pivotal. Dr. Yashwant Sinha and Mr. Arun Jaitley served as Finance Ministers later but are not associated with the 1991 reforms. Given the provided answer, option (2) is considered correct, emphasizing Rao’s leadership role.
