Multiple choiceMediumchapter-4-curatedpremiumcollectionsmap-interface-and-hashmap
Answer and explanation
Correct answer
C. Map<String, Product>
Why
A map is the clearest way to say one key leads directly to one value. If SKU lookup dominates, a Map<String, Product> expresses that intent better than repeatedly scanning a list.
