- Statement 1: The initial phase of disinvestment in India (starting 1991-92) involved selling minority shareholdings in public sector undertakings (PSUs) in small tranches. This is correctly described as the first method. - Statement 2: A later phase, particularly gaining momentum from the late 1990s, involved strategic sale where a significant portion of shares (often majority) was sold, transferring management control to a private entity. This is correctly described as the second method. - Statement 3: The period from 1991-92 to 1998-99 largely saw the use of the first method (minority share sales) to raise revenue and broaden share ownership. - Statement 4: The period from 1999-2000 to 2003-04 (under the NDA government) was marked by a strong focus on strategic disinvestment, which is the second method, aiming for privatization and improved efficiency.
