In which of his following books did Mahatma Gandhi call British Parliament as sterile and prostitute ?

The answer is C, Hind Swaraj. Gandhi wrote it in Gujarati in 1909 as a dialogue between a Reader and an Editor, and it was serialised in Indian Opinion. In it he calls the British Parliament a 'sterile woman and a prostitute', because it keeps changing hands between parties without ever serving the real welfare of the people.

Why the others are wrong:

• A: Sarvodaya was Gandhi's rendering of Ruskin's Unto This Last (1908). It is about welfare economics, not a critique of Parliament.
• B: An Autobiography (1927-29) is a personal narrative of his experiments with truth. It does not contain this remark.
• D: The Story of a Satyagrahi is a narrative about individual satyagraha, not a political treatise on the British legislature.

The core concept here is Gandhi's critique of modern civilisation and parliamentary democracy. For Mains GS-II, this links to debates on representative democracy and whether its institutions serve the people. Hind Swaraj is the text to read for that argument.

Trap: Aspirants pick B because it is Gandhi's best-known book. Read the question for the subject, not the author's fame. A sharp political attack on institutions points to Hind Swaraj.
