Step 1: Recall the three emergencies.
The Constitution allows National Emergency, President's Rule and Financial Emergency.
Step 2: Focus on Financial Emergency.
Article 360 lets the President declare a Financial Emergency if the financial stability or credit of India is threatened.
Step 3: Check India's history.
Even during the 1966 crisis and the 1991 balance of payments crisis, no government invoked Article 360.
Step 4: Compare with the others.
National Emergency has been declared three times and President's Rule many times, but Financial Emergency never.
Step 5: Conclude.
The correct count for Article 360 is zero, that is, never.
Answer: Never (Option 2).
