Aero India 2025, held at the Indian Air Force station in Yelahanka, Bengaluru (10-14 February), is more than an exhibition—it is a hub for innovation, strategic alliances and technological advancement. The 15th edition aims to boost India's self-reliance in defence under Prime Minister Narendra Modi's leadership. The theme 'The Runway to a Billion Opportunities,' underscores India's commitment to cutting-edge defence technology and global collaboration. What began in 1996 as a modest aviation exposition, has, today, evolved into one of the most significant global defence events. With an ever-increasing footprint, Aero India now attracts top-tier defence manufacturers, policymakers, industry leaders and visionaries from across the world. This year, it will surpass past milestones, strengthening India's defence production and technological prowess. A total of 106 OEMs, including 55 foreign firms from 19 countries, like Brazil, France, Israel, Japan, Russia, South Korea, the UK and the US, have confirmed participation. Sixteen defence PSUs and 35 Indian OEMs, including Larsen & Toubro, Bharat Forge, Adani Defence, Mahindra Defence, BrahMos Aerospace, Ashok Leyland Defence, BHEL and ECIL, will showcase advancements, highlighting the growing public-private synergy in India's defence manufacturing. For the first time, the Russian Su-57 and American F-35 fighter jets will be displayed, offering aviation experts and enthusiasts an opportunity to analyse cutting-edge technologies. India will also showcase a model of its fifth-generation 'Advanced Medium Combat Aircraft' (AMCA), featuring 75% indigenous content. Another highlight, 'Manthan,' will promote start-ups and innovation in the aerospace and defence sectors. Aero India 2025 reaffirms India's growing global role in defence and aerospace.
Based on the passage, which of the following best characterises the evolution of Aero India over time?

Comprehension: Read the given passage and answer the questions that follow.
Some of history's greatest masterpieces remain unfinished yet continue to captivate. Leonardo da Vinci's Pilgrimage of the Magi was never completed but remains one of his most important works. Its imperfection invites us to explore not just the end result but the creative process—the artist's journey, struggles and decisions. The lack of polish enhances, rather than diminishes, its power. Life, too, is full of imperfect moments that inspire. True celebration lies not in perfection but in authenticity. The most inspiring people embrace their flaws, struggles and weaknesses, forging connections through honesty rather than an illusion of perfection. They make mistakes, learn and grow, proving that imperfection symbolises progress, growth and potential. When something is lacking, it is not bound by rules and expectations of success. It is free to grow and moves in new directions. Nature reflects this truth—trees grow irregularly, mountains are rugged and flowers bloom asymmetrically. Its beauty lies in rawness and authenticity, transforming imperfections into something extraordinary. Just as nature does not strive for perfection, neither do we. Challenges, mistakes and setbacks shape us. Personal growth is a winding journey, and imperfections propel us forward. Creativity thrives in imperfection. When we seek perfection, art, writing and expression become restricted. But when we embrace mistakes and experimentation, we create something special. Imperfect work holds limitless potential. We connect with those who are real, not perfect—people who endure hardships and evolve. The beauty of human experience lies in shared growth and change. Our flaws unite us, revealing potential in the unfinished, the raw and the ever-evolving.
