B Correct answer
Explanation

Serpent is considered the strongest among these for variable key encryption. It was an AES competition finalist known for its conservative design and high security margins, supporting 128, 192, and 256-bit keys. MARS and Twofish were also AES finalists but Serpent had the highest security margin. DES is weak with only 56-bit keys.
