Correct: C. Reverse or fan grip

Correct: A. Outside line

Bowling on an outside line means targeting the outermost part of the lane (near the gutter) with a large hooking ball that curves back across the lane to hit the pocket from a sharp angle. This line is used by powerful bowlers who generate a strong hook.
