Answer:

Option (b) is the correct answer to this question.

Explanation:

AES is based on Rijndael Algorithm.

The Rijndael algorithm enables a choice of block sizes and key sizes. The choices are for each of 128, 192, or 256 bits. Once NIST implemented Rijndael for AES, it only specified one block size,128 bits, but maintained three major lengths of selection. IEEE 802.11I go a step and further limits when both the main size and length of the block for 128 bits. It simplifies deployment and relieves users during development from having to make yet again another decision.

Other options are incorrect because they are not related to the given scenario.
