Which one of the following is not mentioned as a form of Emergency in the Constitution of India ?

The Constitution of India, under Part XVIII (Articles 352–360), explicitly recognizes three types of emergencies. First, Article 352 provides for a 'National Emergency' (popularly known as a Proclamation of Emergency) due to war, external aggression, or armed rebellion [4]. Second, Article 356 provides for 'President’s Rule', also referred to as a 'State Emergency' or 'Constitutional Emergency', arising from the failure of constitutional machinery in a state [2]. Third, Article 360 provides for a 'Financial Emergency' when the financial stability or credit of India is threatened. While the government may take specific measures during health crises under other statutes like the Epidemic Diseases Act, 1897, or the Disaster Management Act, 2005, the term 'Health Emergency' is not mentioned as a form of emergency within the constitutional framework.
