Explanation:

The Fundamental Rights are meant for promoting the ideals of political democracy. They prevent the establishment of an authoritarian and despotic rule in the country and protect the liberties and freedoms of the people against the invasion by the State. They operate as limitations on the tyranny of the executive and arbitrary laws of the legislature. In short, they aim at establishing ‘a government of laws and not of men’. The Fundamental Rights are named so because they are guaranteed and protected by the Constitution, which is the fundamental law of the land. Hence option 4th is correct.
