Answer: A

Explanation:

The storage administrator is not able to create a new hybrid pool on their Dell Unity XT 680 because the 3.84 TB SSD drives are only supported in all flash pools. Dell Unity XT supports the use of SSDs in all-flash pools, where the entire pool is built from SSD drives, to provide high performance for I/O-intensive workloads.
