Show answer & explanation
Correct answer: B
Correct matching: DES → 56 bits; AES → 256 bits; 3DES → 168 bits; RSA → 1024 bits.
DES: Key size 56 bits. DES is a symmetric block cipher that uses a 56-bit key.
AES: Key size 256 bits. AES supports 128, 192, or 256-bit keys; the match in the list corresponds to the 256-bit variant.
3DES: Key size 168 bits. 3DES applies DES three times using three independent 56-bit keys, giving 3 × 56 = 168 bits.
RSA: Key size 1024 bits. RSA is an asymmetric algorithm that uses much larger key sizes; 1024 bits is the match provided in the list.
Therefore the correct mapping from List I to List II is: DES → 56 bits; AES → 256 bits; 3DES → 168 bits; RSA → 1024 bits.
