Figure 8.1

Note: a hoagie is essentially a submarine sandwich.
-Refer to Figure 8.1.Which of the following statements is true?

A) Quantities Q₀ and Q₁ are the utility-maximizing quantities of hoagies at two different prices of hoagies.
B) Quantities Q₀ and Q₁ may not necessarily be the utility-maximizing quantities of hoagies at two different prices because we have no information on the consumer's budget or the price of other goods.
C) Quantity Q₀ could be a utility-maximizing choice if the price is $5.75, but quantity Q₁ may not be because we have no information on the marginal utility per dollar when price changes.
D) Quantities Q₀ and Q₁ are derived independently of the utility-maximizing model.
