Analyzing the question, we are asked which Python collection maps unique keys to specific values. 
Option 1: 'tuple' — Tuples are ordered, immutable sequences, not mappings; they pair values by position or index, not by unique keys. This makes them unsuitable for key-to-value mapping. 
Option 2: 'list' — Lists are ordered and mutable sequences that hold a collection of items accessed by index, not by unique keys to values; they don’t provide direct key-based lookup semantics. 
Option 3: 'dictionary' — Dictionaries are designed exactly for mapping unique keys to corresponding values; they implement hash-based lookups, enforce key uniqueness, and allow efficient retrieval by key. This aligns with the concept of associating each unique key with a specific value. 
Option 4: 'set' — Sets store unique items but do not associate keys with values; they are for membership testing and eliminating duplicates, not for key-value mappings. 
In summary, the collection that maps unique keys to specific values is the dictionary, since it provides the key-value pairing mechanism and fast access by key, unlike tuples, lists, or sets which serve different structural purposes.
