C. Substitution effect
Explanation:
The substitution effect is the change a consumer makes from one good to another when either of them changes in price. The relationship happens with the so-called substitute goods.

That is, when a good becomes more expensive, the consumer may consider that it is no longer worth buying it. Therefore, it migrates its consumption to a cheaper substitute good. Based on this concept, we can conclude that the substitution effect explains why the idea of Al may not work.
