Correct option is C
Article 21 of the Indian Constitution states that "No person shall be deprived of his life or personal liberty except according to the procedure established by law." Over the years, the Supreme Court of India has interpreted Article 21 in several landmark cases to include a variety of rights under the broader umbrella of the Right to Life.
The Right to Livelihood, Right to Privacy, Right to Dignity, and Right to Hearing have all been judicially expanded from Article 21:
Right to Livelihood was recognized in the Olga Tellis v. Bombay Municipal Corporation case (1985).
Right to Privacy was reaffirmed in the Puttaswamy Judgment (2017), which ruled that privacy is a fundamental right under Article 21.
Right to Dignity has been consistently upheld in numerous rulings, as the essence of life is incomplete without dignity.
Right to Hearing (also known as Audi Alteram Partem) is a principle of natural justice, ensuring that individuals have a chance to be heard before decisions affecting their rights are made.
Articles 19, 20, and 22 address other specific rights related to freedom of speech, protection in respect of conviction for offenses, and protection against arbitrary arrest and detention, respectively. Therefore, the correct answer is (c) Article 21.
