The correct answer is option 3, Delhi. In 2009, the Delhi High Court decriminalized consensual homosexual acts between adults by declaring Section 377 of the Indian Penal Code as unconstitutional. Section 377 criminalized any sexual activities "against the order of nature," including homosexual acts. The Delhi High Court`s verdict stated that the law violated the fundamental rights to equality, liberty, and privacy as enshrined in the Indian Constitution. This landmark judgment brought significant changes to the legal status of gay rights in India. It was a crucial step towards recognizing and protecting the rights of the LGBTQ+ community. The decision was later challenged in the Supreme Court of India, which overturned the Delhi High Court`s ruling in 2013. However, in 2018, the Supreme Court reinstated the rights of LGBTQ+ individuals by decriminalizing homosexuality and striking down Section 377.
