Question: In an MCData (Mission Critical Data) environment, as per 3GPP specifications, what is a prerequisite for a user to successfully create a new folder in their MCData message store?
Option 1: The user must have an active data session with the network.
Option 2: The MCData service must be subscribed to by the user's organization.
Option 3: The user account in the MCData message store must be structured in a folder hierarchy.
Option 4: The User Equipment (UE) must support at least 5G NR (New Radio) connectivity.
Explanation: This is correct because, according to the specifications, creating a new folder is "only meaningful" when the user's account is organized in a folder hierarchy. This implies that without such a structure, the operation would not be applicable or useful, making this condition a prerequisite for the successful execution of the folder creation operation.
