Question: Which entities can utilize SEAL services in the context of Uncrewed Aerial System (UAS)?
Option 1: Only UAE (Unmanned Aerial Equipment) clients
Option 2: Both UAE capabilities (client and server) and UAS application specific servers
Option 3: Exclusively UAS application specific servers, not UAE components
Option 4: Neither UAE nor UAS application specific servers; SEAL services are reserved for other uses
Explanation: This is correct because both the UAE capabilities (including client and server aspects) and potentially the UAS application specific servers can directly utilize the SEAL services, ensuring flexibility and comprehensive support for UAS applications.
