In this problem, we start with a set containing four names, then add two more names and remove one name, and finally print the resulting set. Because sets are unordered collections, the printed representation can show the elements in any order, but the content must reflect the exact elements remaining after the operations.
Option 1: {'Amy', 'Lisa', 'Jane', 'Zoe', 'Amber'}
This option lists exactly the five names that should remain after performing the operations: the initial names Jane, Joe, Amy, Lisa plus Amber and Zoe added, with Joe subsequently discarded. Since sets are unordered, this representation is plausible and contains all and only the expected elements: Jane, Amy, Lisa, Amber, Zoe.
Option 2: {'Jane', 'Joe', 'Amy', 'Lisa', 'Amber', 'Zoe'}
This option includes Joe, who was removed by discard('Joe'). Therefore, this cannot be the actual contents of the set after the code runs.
Option 3: {'Jane', 'Joe', 'Amy', 'Lisa'}
This option omits Amber and Zoe, which were added to the set before the discard operation, so at least Amber and Zoe should be present in the final set. Hence this representation is incomplete.
Option 4: {'Jane', 'Joe', 'Amy', 'Lisa', 'Amber'}
This option includes Joe, which was discarded, and also contains Amber without Zoe, so two aspects are inconsistent with the actual operations: Joe should not be present, and Zoe should be present.
To summarize the logical checks:
- The final set must exclude Joe due to discard('Joe').
- The final set must include Amber and Zoe since they were added and not removed.
- Jane, Amy, and Lisa were present from the original set and remain.
- Any representation missing Zoe or Amber, or including Joe, or omitting any of Jane, Amy, or Lisa, would be incorrect.
Based on these criteria, Option 1 is the one that matches the expected content of the final set after all operations.
