-a 1.0 gigabyte slice 

-a 2.2 gigabyte slice 

-a 9.8 gigabyte slice 

-a 3.2 gigabyte slice 

-a 6.5 gigabyte slice 

Your monitoring software sends you an email indicating that one sub-mirror of a two-way Solaris Volume Manager Software mirror has gone offline because of a hardware error. The sub-mirror that was taken offline was 2.3 gigabytes in size. Which hot spare component will the Solaris Volume Manager software use to recreate the sub-mirror automatically? 

A. The 2.2 gigabyte component 

B. The 3.2 gigabyte component 

C. The 6.5 gigabyte component
