    (C) Double Hashing.

    Explanation:

    Double hashing is technique to counter collision in hashmaps specially in open Addressed hashmaps.

    Collision occurs when we are inserting a key in a hashmap that is already present in the hashmap. Now we have two same keys with different values.

    Double hashing uses a second hash function when there is collision.
