Option (b) is the correct answer: Sarvodaya is a term meaning 'Universal Uplift' or 'Progress of All'. The term was first coined by Mahatma Gandhi as the title of his 1908 translation of John Ruskin's tract on political economy, "Unto This Last", and Gandhi came to use the term for the ideal of his own political philosophy.
Additional information: Gandhi summarized Unto This Last's teachings in these three points:
That the good of the individual is contained in the good of all (The idea of Sarvodaya lies here)
That a lawyer's work has the same value as the barber's, inasmuch as all have the same right of earning their livelihood from their work.
