which is not a property of the Rijndael block cipher algorithm?

Of the following, which is not a property of the Rijndael block cipher algorithm?

A.
It employs a round of transformation that is comprised of three layer of distinct and invertible transformations.

B.
It operates on 64-bit plaintext blocks and uses a 128-bit key.

C.
It is suited for high speed chips with no area restrictions.

D.
It can be used on a smart card.

Explanation:
The Rijndael algorithm was chosen as the AES standard to replace DES.
Its block length and key size can be chosen independently and can be 128, 192 or 256
bits.
