A `PathFinder` class uses a static `cache` that stores routes for the last map loaded. The app now needs several independent maps at once. Which refactor best matches the new requirement?
A
Move the cache into a local variable that is lost after each helper call.
B
Make the cache an instance field of each `PathFinder` and keep only true constants static.
C
Delete all route caching even when each object could cache safely.
D
Make every map static too so all maps share routes.
