Consider the following events: 1. Fourth general elections in India 2. Formation of Haryana State 3. Mysore named as Karnataka State 4. Meghalaya and Tripura become full States Which one of the following is the correct chronological order of the above?

The correct chronological order is 2-1-4-3. Haryana was created on 1 November 1966 by the Punjab Reorganisation Act, so it is the earliest event listed [1]. The Fourth General Elections occurred in February 1967, placing them next [2]. Meghalaya and Tripura were granted full statehood in 1972 (Meghalaya on 21 January 1972 and Tripura in 1972), so these follow the 1967 elections [3]. Finally, the State of Mysore was officially renamed Karnataka in 1973, making this the latest event among the four [3]. Thus the chronological sequence is: Formation of Haryana (2), Fourth General Elections (1), Meghalaya and Tripura statehood (4), Mysore renamed Karnataka (3).
