Message Digest 5 (MD5) is a common hashing algorithm that produces a 128-bithash. Hashes are commonly shown in hexadecimal format instead of a stream of 1s and 0s. For example, an MD5 hash is displayed as 32 hexadecimal characters instead of 128 bits SHA-1 is an updated version that creates 160-bit hashes. This is similar to the MD5 hash except that it creates 160-bit hashes instead of 128-bit hashes

DES is an encryption cipher. MD5 is old and subject to vulnerabilities and collision. So MD5.

Thought B, from the book "The RACE Integrity Primitives Evaluation Message Digest (RIPEMD) algorithm was based on MD4." So, If RIPEMD-160 then should be C, unless I'm missing something....

SHA and RIPEMD are both 160 Weakest is MD5

this explanation makes more sense to understand the answer choice. easy to see how MD5 is the least secure and it is also known to be broken and generating collision.

MD5 is 128bit, but DES is only 56 bits. I go with D

MD5 is a hashing algorithm. DES is an encryption. So, should be C - MD5.
