Explanation
Why Correct: Adequate infrastructure—transport, power, ports, and telecommunications—forms the physical backbone that enables industrial production, distribution, and market access. Without reliable infrastructure, even well-financed and peaceful industrial efforts cannot operate efficiently or scale.
Distractor Analysis: Industrial peace, meaning stable labour-management relations, supports uninterrupted production but cannot substitute for missing roads, electricity, or connectivity. Huge investment by the investor class matters, but investors direct capital only where infrastructure already makes projects viable; poor infrastructure raises costs and deters investment. The denial that infrastructure is the most important factor is false because infrastructure is the foundational enabler.
Takeaway: India's infrastructure deficit has historically constrained manufacturing growth, and the National Infrastructure Pipeline (NIP) was launched in 2019 with a projected investment of over ₹100 lakh crore to address this gap.
