Rijndael has various key sizes and possible rounds. Which of the following is a correct combination when using this algorithm?
A.
If both key and block size is 128 bits, there are 10 rounds
B.
If both key and block size is 128 bits, there are 9 rounds
C.
If both key and block size is 192 bits, there are 11 rounds
D.
If both key and block size is 256 bits, there are 13 rounds
@ Admin: Plz check we are not able to view answer to questions from 1208 – 1300. I have checked this randomly mostly i cant see the right answer when i click “show Answer” Plz check and fix

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.
Thanks Sachin & hh. It’s a mistake.
Fixed.
