The correct answer is option 1, Right to Freedom. The Preventive Detention Act refers to a law that allows the government to detain individuals without trial or charge, usually in order to prevent potential threats to national security or to maintain public order. This act curtails or restricts the right to freedom because it allows the government to detain individuals without following the usual legal processes and safeguards. The right to freedom is a fundamental right guaranteed by most democratic constitutions, including the Indian Constitution. It ensures that individuals are protected from arbitrary arrests and detentions, and are entitled to certain freedoms such as freedom of speech, expression, and movement. The Preventive Detention Act restricts or curtails this right by allowing the government to detain individuals without following these established legal procedures.
