The correct option is A system of collective cultivation of lands by people in rural areas..
Explanation
The "Commune system" was a pivotal socio-economic structure introduced in the People's Republic of China during the Great Leap Forward campaign (1958). It represented an extreme form of a command economy aimed at rapid industrialization and the collectivization of agriculture.
Detailed Analysis:
- A system of privatized farming where peasants owned small plots. is incorrect: The commune system was characterized by the abolition of private property. Peasants did not own small plots; rather, individual land holdings were merged into large collective units.
- A system of collective cultivation of lands by people in rural areas. is correct: Under this system, rural households were organized into People's Communes. These were self-sufficient units where people collectively cultivated the land. The commune controlled all means of production, distributed food through communal kitchens, and managed local governance, education, and healthcare.
- A special economic zone for foreign investment in agriculture. is incorrect: Special Economic Zones (SEZs) and policies encouraging foreign investment were introduced much later, during the economic reforms of the late 1970s (post-1978) under Deng Xiaoping.
- A military conscription program for rural youth. is incorrect: While communes often organized local militias, the primary definition of the Commune system is economic and social collectivization, not military conscription.
Key Takeaway: The Commune system was a method of collective farming and rural organization where land ownership and labor were fully socialized to support a centralized socialist economy.
