Option 1: Only UAE (UAS Endpoint Application) Client
Option 2: Both UAE Capabilities (Client and Server) and UAS Application Specific Servers
Option 3: Exclusively UAS Application Specific Servers via direct Network Management Service procedures
Option 4: Neither UAE nor UAS Application Specific Servers; only external third-party services
Explanation: This is correct because, according to the specification, both the UAE capabilities (which encompass both the client and server aspects) and the UAS application specific servers are mentioned as utilizing the Network Resource Management Service procedures of SEAL. This dual utilization supports the efficient management of network resources for UAS applications and C2 communications, highlighting the collaborative approach in managing network resources within this context.
