Correct answer: C
Chained hashing uses linked lists to handle collisions, allowing direct removal of elements from the list. In contrast, open addressing requires special handling for deleted elements (e.g., marking slots as 'deleted') to maintain search integrity. This makes deletion simpler and more efficient in chained hashing, as no reorganization of the table is needed.
