Why would you reduce the default disk_repair_time parameter?
The correct answer is C. To reduce the amount of data collected for a fast resynch. During transient disk failures within a failure group, ASM keeps track of the changed extents that need to be applied to the offline disk.

Explanation
During transient disk failures within a failure group, ASM keeps track of the changed extents that need to be applied to the offline disk. Once the disk is available, only the changed extents are written to resynchronize the disk, rather than overwriting the contents of the entire disk. This can speed up the resynchronization process considerably. ASM drops disks if they remain offline for more than 3.6 hours. The disk groups default time limit is altered by changing the DISK_REPAIR_TIME parameter with a unit of minutes (M or m) or
