Selected Answer: B
Correct: B Twofish is a symmetric key block cipher with a block size of 128 bits and key sizes up to 256 bits. It was one of the five finalists of the Advanced Encryption Standard contest, but it was not selected for standardization. https://en.wikipedia.org/wiki/Twofish

IDEA and Bluefish both use 64bit block size. HMAC is a hashing algorithm not an encryption algorithm.
