CorrectNot quiteAnswer D

Correct answer: D

When A scores 60, B scores 48 and C scores 42, so C scores $\frac{42}{48} = \frac{7}{8}$ of B's points.
In a game of 80, C scores $80 \times \frac{7}{8} = 70$ : B gives C 10 points.

Worth noting

6 is the gap in A's game of 60; the game here is 80, and B's own pace sets it.
