What is a block cipher algorithm that operates on 64-bit blocks and can have a key length from 32 to 448 bits?

The question has the below multiple choices

A) 3DES
B) RSA
C) Blowfish
D) Twofish

The answer is (C) Blowfish

Also known as the Blow-CAST-Fish, it was designed to run efficiently on 32 bit computers. Up to date no significant weaknesses have been seen. Based on Blow-CAST-Fish, it uses good features of CAST -128[6] algorithms and Blowfish [1]. Features taken from Blowfish [1] algorithm include; S-box entries which are key dependent substitution, varying key lengths of up to 448 bits and procedure of Key expansion
