Explanation
1. Statement 1 is correct: The Persons with Disabilities (Equal Opportunities, Protection of Rights and Full Participation) Act, 1995, which was the primary law in force in 2011, mandated appropriate governments to ensure that every child with a disability had access to free schooling in an appropriate environment until they attained the age of 18 years. This applied to government-run schools and government-aided schools.
2. Statement 2 is correct: Section 43 of the PWD Act, 1995, included provisions for framing schemes for preferential allotment of land at concessional rates to persons with disabilities for purposes such as housing, setting up business, setting up special schools, etc.
3. Statement 3 is correct: Sections 44, 45, and 46 of the PWD Act, 1995, addressed non-discrimination in transport and the built environment. Section 46 specifically required provisions for barrier-free access, including ramps in public buildings, adaptation of toilets, Braille symbols, and auditory signals in elevators.
Therefore, all three statements represent benefits available to persons with disabilities under the law in India in 2011.
