Final answer:
Frank scored n - 6 points, where n represents Jim's score and it is given that Jim scored 6 points more than Frank.
Step-by-step explanation:
The question asks about the relationship between two basketball players' scores. Jim scored n points and Frank scored f points.
If Jim scored 6 points more than Frank, we can express Frank's score as Jim's score minus 6 points. Therefore, the number of points Frank scored would be n - 6, which corresponds to option a) n - 6.
