रोस्टोच्या "स्टेजेस ऑफ इकॉनॉमिक ग्रोथ" मध्ये प्रवेगिक वृद्धिसाठी पुढील आवश्यक पूर्वअट आहे :

The correct answer is Option A (Social Overhead Capital).

Key Points:
• Core Concept
• Walt Whitman Rostow proposed five distinct stages of economic growth: traditional society, preconditions for take-off, take-off, drive to maturity, and age of high mass consumption.
• Why Correct
• In the 'preconditions for take-off' stage, massive investment in social overhead capital (transport, communication, ports, education, and public utilities) is an essential prerequisite for accelerated growth and industrial takeoff.
• Key Details
• Social overhead capital entails long gestation periods and large capital outlays that create external economies for private business.
• Exam Traps
• Candidates often confuse the prerequisites of takeoff with actual takeoff characteristics. Rapid industrial growth is an outcome of the take-off stage, not a pre-condition.
• Other Options
• Option 2 (Higher per capita income) and Option 3 (Rapid industrial growth) are results achieved during or after takeoff.
• Option 4 (FDI) is an external financing mode, not Rostow's theoretical pre-condition.
• Key Takeaway: According to Rostow, the creation of Social Overhead Capital is the primary pre-condition for accelerated growth.
