Answer
Correct order: 3 → 5 → 2 → 6 → 1 → 4
| Order | Statement | Year | Evidence in the text |
|---|---|---|---|
| 1st | 3. Born in pre-independent India | 1913 | “Born in 1913 in Kolkata” — India became independent in 1947, so this is first. |
| 2nd | 5. Joined the University of Manchester under Blackett | 1945 | “In 1945, Bibha's academic journey took her to the University of Manchester.” |
| 3rd | 2. First woman faculty member at TIFR | 1949 | “In 1949, upon her return to India, she became the first woman faculty member at the Tata Institute of Fundamental Research.” |
| 4th | 6. Nominated for a Nobel Prize by Schrödinger | 1950 | “Her nomination for a Nobel Prize in 1950 by Erwin Schrödinger…” |
| 5th | 1. IAU renames the star HD 86081 as ‘Bibha' | 2019 | “In 2019, the International Astronomical Union (IAU) honoured her legacy…” |
| 6th | 4. Chair professorship declared in her name | 2020 | “In 2020, the Government of India declared a chair professorship in her name.” |
How to solve this kind of question reliably: the text gives four dates outright (1945, 1949, 1950, 2019, 2020) — copy them out first and the sequence almost writes itself. Only statement 3 has no year attached, and the phrase ‘pre-independent India' places it before 1947, which is earlier than every other event. Note also that she died in 1991, so the last two honours are posthumous — she never knew of either.
