“A quorum failure group is a special type of failure group that does not contain user data. Quorum failure groups are used for storing Oracle ASM metadata. A quorum failure group may also contain voting files if those files are stored in a disk group that contains a quorum failure group. Additionally, Oracle ASM uses a quorum failure group to help determine if the disk group can be mounted in the event of the loss of one or more failure groups.” – https://docs.oracle.com/database/121/OSTMG/GUID-BF6AA37D-36CC-4D1F-97EF-80FB2A20FEFE.htm#OSTMG10204
See, “… may also contain … , it’s not a requirement.
Correct: A, B
