A Correct answer
Explanation

For multiplexed redo logs with redundancy, you need at minimum 3 disks - each member of each redo log group should be on a separate disk to protect against disk failure. With 2 groups and 3 members each, multiplexing requires 3 distinct disks to ensure no single disk failure causes loss of all members of any log group.
