B.
It allows the initiator to query the target about path attributes, such as primary path and
secondary path.
C.
It is a set of SCSI commands for discovering and managing multiple paths to LUNs on Fibre
Channel SANs.
D.
It requires Array Support Library (ASL), a proprietary vendor library.

access, second para)
I think there is no 100% good answer for this question. The referred article is about 7-Mode. My concerns are the followings:
1. The “A” is also a good answer. No configuration is required. ALUA is enabled by default.
2. The answer “C” is not perfect. ALUA is supported and enabled by default on both FC and iSCSI.
