A. B. C. D. E.A.
When considering a megacluster deployment, the primary areas impacting capacity are as follows: The megacluster may contain a total of 21 servers consisting of 16 subscribers, 2 TFTP servers, 2 music on hold (MoH) servers (0 required), and 1 publisher Server type must be either Cisco MCS 7845-I3/H3 class or Cisco Unified Computing System (UCS) C-Series or B-Series using the 10K Open Virtualization Archive (OVA) template.
Redundancy model must be 1:1

In a Cisco Unified Communications Manager Session Management Edition (SME) trunk-only megacluster, music on hold (MoH) can be provided by a centralized MoH server or by each individual Cisco Unified Communications Manager in the megacluster.
So, the number of required MoH servers in a trunk-only megacluster of Cisco Unified Communications Manager SME depends on the selected deployment model.
If a centralized MoH server is used, then only one MoH server is required for the entire megacluster. In this deployment model, all calls placed on hold within the megacluster are served by the centralized MoH server.
If each individual Cisco Unified Communications Manager in the megacluster is used for MoH, then the number of required MoH servers will depend on the number of Cisco Unified Communications Manager servers in the megacluster.
Therefore, the answer to the question depends on the selected deployment model. If a centralized MoH server is used, the answer is 1 (option B). If each individual Cisco Unified Communications Manager in the megacluster is used for MoH, the answer will depend on the number of servers in the megacluster. However, this is not specified in the question, so we cannot determine the correct answer in this case.
