The correct option is Restore its freshness
Explanation
The location of agro-based industries is primarily determined by the nature of the raw material. For industries using perishable raw materials, the processing units must be located near the source of production to prevent spoilage and loss of quality.
Analysis of the Options
- Restore its freshness Restore its freshness: Correct. Tea leaves are highly perishable. Once plucked, the leaves begin to lose moisture and ferment rapidly. If they are not processed immediately, they lose their distinct flavor and quality. Therefore, tea processing factories are located within the tea gardens to process the green leaves instantly, ensuring the retention of their essential qualities (often described in standard geography texts as "restoring" or preserving freshness).
- Reduce transportation costs Reduce transportation costs: Incorrect (Secondary Factor). While tea is a weight-losing raw material (processed tea is much lighter than green leaves), and locating the factory near the source does reduce transport costs, the primary imperative for locating the factory within the garden is the perishability of the leaf. If transport cost were the only factor, the factory could be located nearby but not necessarily within the estate; however, the need to arrest fermentation dictates the immediate proximity.
- Avoid taxation Avoid taxation: Incorrect. Taxation policies are administrative and do not dictate the physical location of processing units relative to the fields in this context.
- Provide employment to locals Provide employment to locals: Incorrect. While the tea industry is labor-intensive and provides significant employment, this is a socio-economic outcome, not the primary technical reason for the location of the processing plant.
Key Takeaway
Tea processing is located within tea gardens primarily due to the
perishability of tea leaves, which must be processed immediately to preserve their flavor and freshness.
