The Subsistence Theory of Wages, formulated by the French Physiocrats and classical economist David Ricardo, was termed the 'Iron Law of Wages' (Eisernes Lohngesetz) by socialist thinker Ferdinand Lassalle. The theory posits that in the long run, market wages inevitably tend toward the minimum subsistence wage required for a worker and family merely to survive and reproduce.

Option analysis:

• LEMU: Law of Equi-Marginal Utility.
• LDMU: Law of Diminishing Marginal Utility.
• Scarcity Law: General economic concept.
• Iron Law of Wages: Correct alternative name for the subsistence wage theory.

In cooperative farming taxonomy:

• Cooperative Joint Farming: Farmers pool their individual land parcels for joint cultivation and management. Individual ownership of land is strictly retained, and net farm profits are distributed among members based on the land area contributed and labor performed.
• Cooperative Collective Farming: Land ownership is surrendered permanently or held collectively by the society (kolkhoz model).
• Cooperative Better Farming: Farmers cultivate independently on their own plots but join hands only for input purchase or marketing.
• Cooperative Tenant Farming: Society owns or leases the land and sub-leases plots to tenants who cultivate independently.
  
  Option analysis:
• Cooperative joint farming system: Correct, retains land title while pooling operations and sharing profits proportionally.
• Cooperative collective farming system: Individual land ownership is relinquished.
• Cooperative better farming system: Operations are not pooled.
• Cooperative tenant farming system: Land belongs to society, not individual holdings.

For commercial cash crops (like cotton, sugarcane, and jute), the entire output is marketed, so a higher price unambiguously increases marketed surplus (positive elasticity). In contrast, for staple subsistence food grains like Rice, smallholder farmers retain a large fraction of production for home consumption. When the price of rice rises, the substantial income effect allows subsistence farm families to consume more rice and sell less, resulting in an inverse (negative) price elasticity of marketed surplus (backward-bending supply curve of marketed surplus, as analyzed by P.N. Mathur and H. Ezekiel).

Option analysis:

• Rice: Correct, staple food grain exhibiting negative price elasticity of marketed surplus in subsistence agriculture.
• Cotton: Pure commercial fiber cash crop (positive supply response).
• Sugarcane: Commercial cash crop with strictly positive marketed surplus response.
• Jute: Commercial fiber cash crop with positive price response.
