Answer:
D. Number of Potential Customers
Explanation:
The population of a state is the total number of the potential customers in the state. When there is a 25% decrease in the population, this means that the potential customers have reduced by 25%.

However, the decrease in population might not increase the number of potential customer of Cheese pizza if the decrease in population does not include any of the sector ( probably an age range of cheese pizza customers).
