  4. D3, 4, 2, 1

Explanation

To determine the correct chronological sequence, we need to look at the years these historical events took place: 1. Formation of Bangladesh: This occurred in December 1971 following the Indo-Pakistani War. 2. Pokhran-I test: India conducted its first nuclear test, codenamed Smiling Buddha, in May 1974. 3. Sikkim becomes the 22nd State: Sikkim officially joined the Indian Union as a full state in May 1975 after the 36th Constitutional Amendment Act. 4. SLV-3 Launch: India successfully launched its first satellite launch vehicle, SLV-3, which placed the Rohini satellite into orbit in July 1980. Following this timeline, the sequence is 1971, 1974, 1975, and 1980. This corresponds to the order 2, 4, 3, 1. Therefore, Option A is the correct answer.
