Choose the correct answer from the options given below:
Answer is (C).
(Even in cryptographic hash functions collision happens, just that it is not easy to find colliding instances).
A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. The values are usually used to index a fixed-size table called a hash table. Use of a hash function to index a hash table is called hashing or scatter storage addressing.
