Correct answer: B
Concept
A computing cluster has functional layers. The access layer exposes interfaces to users, the middleware layer coordinates distributed resources and supplies system-wide services, compute nodes execute tasks, and storage preserves shared data.
Application
The stem groups communication, resource management, job scheduling, fault-tolerance, and security. These are coordination services that must operate across multiple machines rather than being confined to a user interface, one execution node, or a storage system.
Contrast
User Access handles job submission, monitoring, and result retrieval at the user-facing boundary.
Cluster Middleware coordinates the nodes and exposes common services such as communication, scheduling, resource allocation, fault handling, and security.
Compute Nodes provide the processing and memory on which scheduled jobs run.
Shared Storage provides persistent files and datasets accessible across the cluster.
Result
Therefore, the service-providing coordination layer described in the question is Cluster Middleware.
