   A script needs to store a list of server hostnames and later check if a specific hostname exists in the list. The list may contain duplicate hostnames, but the script only needs to know if a hostname is present. Which data structure is most efficient for this membership test?

   • AA set, because it provides O(1) average-time membership testing and automatically removes duplicates.
   • BA tuple, because it is immutable and faster than a list.
   • CA list, because it preserves order and allows duplicates.
   • DA dictionary, because it can store key-value pairs.
