Concept:Subsistence agriculture is the practice of producing food primarily for the farmer's own household needs.
Explanation:In subsistence agriculture, the farmer grows crops and rears animals mainly to feed the family.
The scale of production is small and the output is mostly consumed at home.
There is little or no surplus left for sale in the market.
This system typically uses simple tools and relies less on advanced technology.
The main goal is self-sufficiency and survival rather than earning profit.
Hence, option C matches the definition exactly.
Options A and D describe commercial agriculture, which is market-oriented and large-scale.
Option B describes intensive, technology-driven farming, which is not subsistence farming.
Answer:C. Farming for self-sufficiency and survival
