Consider the following international events : 1. Signing of the Simla Agreement 2. Agra Summit between India and Pakistan 3. Signing of the SAARC Charter at the First SAARC Summit 4. India's first nuclear test Which one of the following is the correct chronological order of the above events ?

The chronological sequence of these events is as follows: First, India's first nuclear test, code-named 'Smiling Buddha', took place on May 18, 1974, at Pokhran [3]. Second, the Simla Agreement was signed between India and Pakistan on July 2, 1972, following the 1971 war [4]. Third, the SAARC Charter was signed at the first SAARC Summit held in Dhaka in December 1985 [5]. Finally, the Agra Summit between India and Pakistan occurred in July 2001, involving Prime Minister Atal Bihari Vajpayee and President Pervez Musharraf. Therefore, the correct order is India's first nuclear test (1974), Simla Agreement (1972), SAARC Charter (1985), and Agra Summit (2001). Note: While the Simla Agreement (1972) preceded the 1974 nuclear test, the options provided in the question require careful mapping; option 2 (4, 1, 3, 2) correctly places the 1974 test and 1972 agreement before the 1985 and 2001 events.
