Concept:
• The Preamble of the Indian Constitution defines the core values and the nature of the Indian polity.
• Each term used in the Preamble has a specific political and legal meaning.
Step 1: Define Sovereignty
Sovereignty implies that the State has absolute and independent authority over its territory and is not subject to any external power.
Thus, A matches with III.
Step 2: Define Republic
A Republic is a form of government where the Head of State is elected, directly or indirectly, and is not a hereditary monarch. The power rests with elected representatives.
Thus, B matches with II.
Step 3: Define Democracy
As famously defined by Abraham Lincoln, democracy is a system of government of the people, by the people, and for the people.
Thus, C matches with I.
Step 4: Define Secular
In the Indian context, secularism (Sarva Dharma Sambhava) means that the State treats all religions equally and does not have an official state religion.
Thus, D matches with IV.
Step 5: Final Matching
The sequence is A-III, B-II, C-I, D-IV.
This corresponds to option (C).
