D1 and S1 show the original demand and supply curves for a product. D2 and S2 indicate the corresponding curves after market conditions change. What are the resulting changes in consumer and producer surplus?
- Achange in consumer surplus: from R to P; change in producer surplus: from U to Q
- Bchange in consumer surplus: from R + T to P; change in producer surplus: from U to Q + R
- Cchange in consumer surplus: from R + T to P; change in producer surplus: from V to Q
- Dchange in consumer surplus: from R to P + S; change in producer surplus: from V to Q + R
