The case arose from a scooterist who was left without timely medical help after an accident because doctors were hesitant to treat him without first involving the police. That background is the key to matching it to the right answer.
- Right to clean and healthy environment: Nothing in the facts of Parmanand Katara touches on environmental harm, so this option can be dismissed immediately.
- Right to speedy trial: The case is not about how quickly a criminal trial proceeds; it is about how quickly medical help must reach an injured person, so this too is unrelated.
- Right to life and personal liberty: The ruling is grounded in Article 21, but this option describes the constitutional source in general terms rather than the specific rule the Court laid down about emergency treatment.
- Right to emergency medical care: This captures exactly what the Court decided, that legal formalities must never delay urgent treatment and that every hospital, government or private, owes a duty to treat an injured person first.
Given the facts of the case and the specific rule the Court announced, the right most directly associated with it is emergency medical care.
Therefore, the correct answer is Right to emergency medical care.
