Indian Historical Events Chronology

The correct chronological sequence is: (4) Goa became part of India in 1961; (2) Imperial Bank of India was renamed State Bank of India in 1955; (1) First democratically elected communist government formed in Kerala in 1957; (3) Air India was nationalised in 1953. Therefore, the sequence is 4-2-1-3. Event 4 happened last (1961), making option (c) correct. Option (a) places event 1 before event 2, which is incorrect. Option (b) places event 3 first, which is wrong as Air India was nationalised in 1953, before the Kerala election in 1957. Option (d) also has incorrect ordering. > Remember: Goa accession (1961) → SBI renamed (1955) → First communist govt (1957) → Air India nationalised (1953). Wait, rechecking: Air India nationalised 1953, SBI renamed 1955, Kerala communist govt 1957, Goa accession 1961 = 3-2-1-4. But option (c) is 4-2-1-3. Recheck: Air India 1953, SBI 1955, Kerala 1957, Goa 1961 means sequence should be 3-2-1-4 which is option (b). Answer: (b).
