C. Hash Table

Detailed Explanation

A Hash Table is designed to provide efficient searching, insertion, and deletion. With a good hash function and a suitable load factor, these operations typically take O(1) average time. A hash table stores data using key-value pairs, where a hash function converts a key into an index. Collisions can occur when multiple keys map to the same index, so techniques such as chaining and open addressing are used to handle them.
