In his autobiography, 'The Story of My Experiments with Truth', Mahatma Gandhi identifies John Ruskin’s 'Unto This Last' as a book that brought about an instantaneous change in his life. He summarized the teachings of the book into three fundamental points:

1. The good of the individual is contained in the good of all.
2. A lawyer's work has the same value as the barber's, as all have the same right of earning their livelihood from their work.
3. A life of labour, i.e., the life of the tiller of the soil and the handicraftsman, is the life worth living. Gandhi later translated the book into Gujarati under the title 'Sarvodaya' (The Welfare of All). Option B directly reflects the first principle, which Gandhi considered the core message that transformed his philosophy.
