The block cipher algorithm that operates on 64-bit blocks and can have a key length from 32 to 448 bits is known as Blowfish. Both AES and 3DES operate on 64-bit blocks, but they have fixed key lengths (128 and 168 bits for AES, and 56 or 112 bits for 3DES). RSA is not a block cipher algorithm, but rather a public-key encryption algorithm. Therefore, the best choice is C, Blowfish.
