Concept:Utility is a personal and subjective experience.
Explanation:Interpersonal utility comparison means comparing the satisfaction that different people get from consuming a good.
This is impossible because each person’s satisfaction depends on their own tastes, preferences, and circumstances.
Utility cannot be measured objectively or observed directly from outside.
Since satisfaction is unique to each individual, we cannot accurately say that two persons derive the same level of satisfaction from the same item.
Such comparisons can only be based on subjective values, not on any reliable common measure.
Answer:C. utility is subjectively determined.
