C Correct answer
Explanation

From the conditions: U's test score equals A's quiz score. Since A's quiz score is given as 80, U's test score must be 80. This is a direct application of the given relationship.

AI explanation

Working through the clues: A's quiz score = 80. A's test score equals U's quiz score. U's test score equals A's quiz score, so U's test score = 80. A's quiz score is 15 less than U's quiz score, so U's quiz score = 80 + 15 = 95, which means A's test score = 95 (since A's test = U's quiz). But the question asks for U's test score specifically, which was already established as equal to A's quiz score = 80. So U's test score = 80, matching the marked answer. The other options (55, 65, 95, 100) either confuse U's test score with A's or U's quiz score, or don't follow from the given equations at all.
