Concept:
Disguised unemployment is a situation where more workers are engaged in an activity than are actually required. Some workers appear to be employed, but their contribution to production is negligible or zero.
Step 1: Understand disguised unemployment.
Suppose a farm requires only five workers to produce a certain quantity of crops.
If eight workers are employed on the same farm:
• Production remains unchanged.
• Three workers are effectively unnecessary.
• Those workers are disguisedly unemployed.
Step 2: Occurrence in agriculture.
This type of unemployment is commonly observed in:
• Rural areas.
• Family farming.
• Traditional agricultural activities.
Agriculture is therefore the classic example used in economics.
Step 3: Why not other options?
Though overemployment may occur elsewhere, disguised unemployment is most characteristically associated with agriculture.
Hence the option mentioning agriculture is the most accurate.
Step 4: Conclusion.
Disguised unemployment refers to employment of more workers than necessary in agriculture.
Hence, option (C) is correct.
