What did India become after the Constitution came into force?

Republic

When the Constitution of India came into force on 26 January 1950, India became a republic. In a republic, the head of the state is not a hereditary monarch; the office is established through constitutional and representative procedures. This marked the formal beginning of India’s constitutional democratic system and gave effect to the principles adopted by the Constituent Assembly. Republic Day is observed on 26 January each year to remember this event.

Choice A is correct. A colony is controlled by an outside power, a princely state refers to a pre-independence form of rule, and an empire is associated with imperial authority and expansion. None describes India’s constitutional status after 1950. The important distinction is that independence came in 1947, while becoming a republic followed when the Constitution took effect in 1950.
