Among the following States, which one was formed last ?

Based on the chronology of state formation in India, Haryana was the last state to be formed among the given options. Rajasthan was established in 1949 through the merger of princely states [t1]. Andhra Pradesh was the first linguistic state, created in 1953 from the Madras State [c1][c3]. Gujarat was formed in 1960 following the bifurcation of the bilingual Bombay State under the Bombay Reorganisation Act [c1][c2]. Haryana was carved out of the state of Punjab on November 1, 1966, following the Punjab Reorganisation Act, to accommodate the Hindi-speaking population [c1][c2][c4]. Therefore, while Rajasthan (1949), Andhra Pradesh (1953), and Gujarat (1960) were established earlier, Haryana's formation in 1966 makes it the most recent among the four choices provided.
