Solution
✅ Correct Option: 4
Tea and coffee are substitute goods. A rise in the price of tea induces consumers to demand more coffee at every price of coffee. Since the change is caused by the price of a related good (not coffee's own price), the entire demand curve for coffee shifts rightward; a movement along the curve occurs only for own-price changes.
