भारताच्या पहिल्या दोन पंचवार्षिक योजनांमध्ये वाटपाचा सर्वात जास्त हिस्सा _____या एका क्षेत्राला मिळाला.

The correct answer is Option D (Transport and Communication).

Key Points:
• In India's first two Five Year Plans (First Plan 1951-56 and Second Plan 1956-61):
• The First Five Year Plan focused heavily on agriculture, irrigation, and power, but the single largest outlay went to agriculture and irrigation combined, whereas in the Second Plan the Mahalanobis strategy shifted to heavy industries and infrastructure.
• However, looking at overall cumulative allocations across the first two plans combined or individually in terms of infrastructure categories, Transport and Communication (infrastructure, railways, roads) received the highest single sectoral share in the early plans (e.g., ~24% in the First Plan and ~28% in the Second Plan).
• Transport and Communication consistently claimed the top single allocation position in the initial plan budgets.
• Therefore, Option (4) is the correct answer as per the official answer key.
• Key Takeaway: Transport and Communication received the highest single sectoral financial allocation in India's first two Five Year Plans.
