The Question asked is wrong. It should be “Which of the following is a correct combination when using this algorithm? ” ….. NOT should be removed from the question. If the question is asking not then B,C & D are right answer

• If both the key and block size are 128 bits, there are 10 rounds.
• If both the key and block size are 192 bits, there are 12 rounds.
• If both the key and block size are 256 bits, there are 14 rounds
The question should be which is a correct combination.
