Option 1 -> This is only the value added by the farmer, not the total value added in the entire process.
Option 2 -> This represents the total value added across all stages of production from raw cotton to final garments.
Option 3 -> This is an incorrect calculation that doesn't match the value addition methodology.
Option 4 -> This appears to be the sum of all transaction values, which is not how value addition is calculated.
Hence, Option 2: Rs 9000 -> Value addition at each stage: Farmer (Rs 2500 - 0 = Rs 2500), Yarn firm (Rs 4000 - Rs 2500 = Rs 1500), Cloth mill (Rs 6500 - Rs 4000 = Rs 2500), Garments factory (Rs 9000 - Rs 6500 = Rs 2500). Total = Rs 2500 + Rs 1500 + Rs 2500 + Rs 2500 = Rs 9000. Alternatively, since the farmer has no intermediate cost, total value added equals the final selling price, which is Rs 9000. -> correct
