If the price of commodity X rises and consumers shift to commodity Y, then commodities X and Y are
- inferior goods
-
substitutes
- complements
- bought together
The correct answer is: B
Explanation
Substitutes are goods that can be used in place of each other to satisfy a similar need or want. When the price of commodity X increases, consumers may find that commodity Y offers a comparable benefit at a lower cost, prompting them to switch their consumption from X to Y. The increase in the price of X leads to a higher demand for Y, indicating that the two commodities are substitutes.
