Final answer:
MD5 is the weakest hashing algorithm among the given options.
Step-by-step explanation:
Out of the given options, MD5 is the weakest hashing algorithm. MD5 (Message Digest Algorithm 5) is a widely used hashing algorithm that produces a 128-bit hash value. However, it is considered weak because it is vulnerable to collision attacks, where different inputs can produce the same hash value. This makes it less secure compared to the other options.
