- Statement 1 is correct: Section 377 of the IPC criminalized 'unnatural offences', including consensual same-sex relations, and its decriminalization was a significant step for LGBTQ+ rights in India. - Statement 2 is correct: Joseph Shine vs Union of India is the landmark case where the Supreme Court struck down Section 497 of the IPC (adultery) as unconstitutional. - Statement 3 is correct: Indian Young Lawyers Association vs State of Kerala is the Sabarimala temple entry case, which challenged the denial of entry to women of menstruating age, directly relating to women's rights and equality in religious places. - Statement 4 is incorrect: Yashwant vs State of Maharashtra deals with criminal law matters and is not associated with the Right to Education. The Right to Education is primarily linked to Article 21A of the Constitution and related legislation/cases like Unni Krishnan case or those concerning the RTE Act, 2009.
