Answer: B

Explanation:

NTP (Network Time Protocol) uses the MD5 (Message-Digest Algorithm 5) hashing algorithm for authentication purposes. MD5 is utilized to create a hash value based on the time information being sent over the network. This hash is then used to verify the integrity and authenticity of the NTP messages, ensuring that the time data has not been tampered with during transit. While MD5 is not the most secure hashing algorithm available, it is widely used in NTP implementations due to its balance of security and computational efficiency.
