उत्तर और व्याख्या · explanation in English
Answer: (a) तंबाकू, कोको और रबड़
The 'New World' is the Americas; the 'Old World' is Asia, Africa and Europe. Tobacco, cacao (cocoa) and Para rubber are all American plants that Europeans carried across the Atlantic after 1492. Every other option contains at least one Old World crop.
- ✓ (a) Tobacco was used by Native Americans before Europeans adopted it; cacao is native to the Amazon and Orinoco basins; the rubber tree (Hevea brasiliensis) is native to the Amazon basin and was later planted in Asia.
- ✗ (b) Cotton was domesticated independently in South Asia as well — traces are found at Harappan sites — so it is not solely a New World gift.
- ✗ (c) Coffee comes from Ethiopia and sugarcane from South and Southeast Asia, both Old World crops.
- ✗ (d) Wheat was domesticated in West Asia, and coffee in Africa; only rubber here is American.
Remember · Columbian Exchange, Americas → Old World: tobacco, cocoa, rubber, maize, potato, tomato, chilli, groundnut, pineapple, papaya. Old World → Americas: wheat, sugarcane, coffee.
