A recent movie titled The Man Who Knew Infinity is based on the biography of

The answer is A) S. Ramanujan. The 2015 film The Man Who Knew Infinity, directed by Matt Brown with Dev Patel as Ramanujan and Jeremy Irons as G. H. Hardy, follows Robert Kanigel's 1991 biography of the same name. It covers Ramanujan's (1887-1920) years at Trinity College, Cambridge, from 1914 under Hardy, and his election as a Fellow of the Royal Society in 1918.

• B) S. Chandrasekhar: He won the Nobel Prize in 1983 for work on stellar structure, including the Chandrasekhar limit for white dwarfs. He is not the subject of this film.
• C) S. N. Bose: Bose-Einstein statistics and the boson are named after him. The film has no connection to his life.
• D) C. V. Raman: He won the 1930 Nobel Prize for the Raman effect. He is unrelated to this film.

Core concept: biographical films and books on Indian scientists, a recurring theme in the Art and Culture and Science and Technology sections. For Mains, Ramanujan's story prompts discussion of talent, institutional support, and the colonial-era hurdles faced by Indian researchers.

Trap: candidates pick Chandrasekhar because of the Nobel and Cambridge link. Identify the person from the film's subject, not from the prize record.
