The correct answer is option 1: a proclamation of National Emergency.
Fundamental Rights are a set of basic rights guaranteed to all citizens of India by the Constitution. These rights are considered fundamental because they are essential for the development and well-being of individuals and society as a whole. However, in certain exceptional circumstances, these rights can be suspended temporarily.
Option 1 states that the Fundamental Rights can be suspended only by a proclamation of National Emergency. A National Emergency can be declared by the President of India when there is a threat to the security of the country, whether due to war, external aggression, or armed rebellion. During a National Emergency, the government is granted special powers to take necessary measures to address the emergency situation, and this may involve suspending certain Fundamental Rights for a limited period.
Options 2, 3, and 4 are incorrect. While the Parliament can pass laws and the Constitution can be amended, they cannot suspend the Fundamental Rights directly. Similarly, judicial decisions of the Supreme Court can interpret and safeguard the Fundamental Rights, but they cannot suspend them.
Therefore, the correct answer remains option 1: a proclamation of National Emergency.
