Refer to Figure 6.15. Jason is not maximizing his utility at point

A) E.
B) B.
C) C.
D) All of the above are correct.

Without access to Figure 6.15, we can infer that if all the given options (E, B, C) are presented as points where Jason is not maximizing his utility, the correct answer must be that he is not maximizing his utility at any of the listed points, hence "All of the above are correct." Utility maximization occurs when a consumer allocates their budget in a way that maximizes their satisfaction, and if multiple points are suggested where this is not happening, it implies a failure to maximize utility at each.
