Concept:The illustrated farm operation is staking, which supports weak or climbing crop stems.
Explanation:Staking helps improve the yield of crops by keeping plants upright and healthy.
It exposes leaves to sunlight, which improves photosynthesis and growth.
Staking also prevents lodging of the plants, as the support keeps stems erect.
However, staking does not prevent damage by rodents, because rodents attack fruits, roots, or stored parts at ground level.
Thus, preventing rodent damage is not a reason for carrying out the staking operation.
Answer:C. Prevent damage by rodents.
