Solution
Option 1 -> Captures the comprehensive scope of the passage covering global solar innovations and India's transformative role in the "global solar revolution."
Option 2 -> Too narrow; focuses only on government schemes while the passage also discusses global innovations, declining costs, and the broader solar industry transformation.
Option 3 -> Too generic; the passage specifically focuses on solar power rather than renewable energy in general, and emphasizes present achievements alongside future goals.
Option 4 -> Inaccurate and overstated; the passage describes India as a "prominent player" not a dominant force, and includes significant discussion of global solar developments.
Hence, Solar Power Revolution -> This title best encapsulates the passage's central theme of transformative change in solar energy, covering both groundbreaking innovations worldwide and India's monumental growth from technological advances to policy initiatives, all contributing to what the passage explicitly calls a "global solar revolution" -> correct
