Answer: B

Explanation:

A sysplex is a collection of z/OS systems that cooperate, using certain hardware and software products, to process work. It is a clustering technology that can provide near-continuous availability. A Parallel Sysplex is a sysplex that uses multisystem data-sharing technology

A Parallel Sysplex is a cluster of IBM mainframes acting together as a single system image with z/OS. Used for disaster recovery, Parallel Sysplex combines data sharing and parallel computing to allow a cluster of up to 32 systems to share a workload for high performance and high availability.
